Seattle based wiki-startup Wetpaint has been talking to a number of big content sites about a new product they’ll be releasing soon, we’ve heard. The screen shot above is a mock-up that Wetpaint is using to pitch potential partners.

The product is an embeddable wysiwyg wiki. That alone is interesting, just because there aren’t any easy ways to embed a wiki into third party sites today. Google Sites doesn’t yet allow embeds, for example. PBWiki, a popular wiki startup, does allow embeds via their API, but it isn’t as simple to use as most widgets.

But what we’re hearing is that this isn’t a simple javascript or Flash embed. It’s a deeper integration that requires an insertion of code into a site’s back end application files. That allows the wiki to be created at the server level, not simply rendered in the user’s browser like most widgets. The idea is a pretty straightforward way to go about doing this, although we haven’t heard of any products doing this before.

Why is that interesting? It’s interesting because it pulls the Wiki content directly into a site’s HTML and allows it to be indexed by search engines. That means partner sites will get the SEO benefits of the wiki, a major plus for these partners.

That’s all we know for now. The product is being called Balco, although that may be an internal project name, not the name of the to-be-launched product. If Balco is as useful as we’re hearing, it’s definitely something we’ll use here at TechCrunch.

Update: PBWiki’s David Weekly adds something related to this in his API documentation (scroll to bottom). When/if Wetpaint launches Balco, we’ll do a side by side comparison.

As Google gets into the wiki space with Google Sites (the relaunch of Jotspot), all the other little wiki startups out there will need to keep one step ahead. Those includes Wikia, Socialtext, Wetpaint, and PBWiki. As it approaches 500,000 wikis, PBWiki is now putting the 2.0 version of its site into beta. The latest version includes an updated UI, folders, enhanced access controls and an easy way to customize the look and feel of your wiki page (see the screenshot of a customized TechCrunch page below or this generic demo page). The 2 million people a month that the company says visit PBWiki should like that.

Personally, I find the UI to still be something that an engineer would love more than a graphic designer. But it is an improvement. Adding skins is a move in the right direction. What’s your favorite wiki?

Seattle-based Wetpaint, which launched in June 2006, is a hosted wiki site that focuses on great looking sites and making the user interface as easy as possible. A number of wikis have popped up around popular pop culture stuff, as well as more private sites.

Tonight they added new feature that should generate a lot of page views – they have fully integrated a forum/message board into every wiki.

This isn’t Tangler-level forums (which we consider to be the bleeding edge), but they’ve put a lot of thought into the feature set around these message boards. Posts can be tagged, the view expanded/contracted, there are email notifications of new messages, and the search feature works well. Any forum thread can also be turned into a wiki with a couple of clicks.

CEO Ben Elowitz says the two products go together well – wikis are great for evergreen content but don’t allow for good conversation. Forums allow great conversation but aren’t great for new readers. The hope is that by combining them they’ll allow for better content for all users. And in the process get a lot of page views.

Other startups innovating in the forum space (besides Tangler, mentioned above) are Meetro and Grouply.

The hosted wiki space is crowded, and Wetpaint competes with Wikia and PBWiki, among others. Comscore shows Wikia in the lead with over 3 million monthly uniques, followed by Wetpaint with 1.3 million and PBWiki with 770k (Wikipedia, of course, is the 800 pound gorilla, with 228 million unique monthly visitors):

PBWiki is on a bit of a roll. After confirming a $2 million round of financing last week, they’ve just launched a partnership with 30Boxes that allows users to insert a calendar into a wiki. Actually getting the calendar into the wiki requires way too many steps, and I agree with 30Boxes founder Narendra Rocherolle that this should be made into a template option, as Jotspot did in 2006, shortly before their acquisition by Google.

Wikis are basically commodities at this point. There are dozens of hosted and unhosted versions to choose from, and revenue models are pretty thin. PBWiki has a loyal following of users, though, and has spent very little money getting to where they are today. We’ll see how they do over the next year.

PBwiki closed $2 million in funding this morning from Mohr Davidow Ventures.  Founder and CEO David Weekly confirmed that previous investors Ron Conway and Chris Yeh also put in an additional $100k.

PBwiki advertises itself as the easiest way to quickly create a hosted wiki and the company’s product is particularly well executed.  It recently added a What You See is What You Get editor, which if satisfactory to new users, could help PBwiki overcome one of the primary barriers to wiki adoption.  The recent upgrade also added the ability to include YouTube videos, Flickr photostreams, stock charts and chat functionality to your wikis.  Chat will likely be useful but I question how many of their users will be excited about the rest of the new features.  PBWiki’s basic features are what make it shine.

Weekly told me that there are more than 200,000 PBwikis and a substantial portion of them have been active in the past 60 days.  (My ten sleeping PBwikis notwithstanding, apparently.)  Weekly says the ads on free accounts make less than 5% of the company’s revenue; premium accounts are available for between $10 and $35 per month.  He says the 8 person company brings in enough money to be “profitable some months.”

Weekly says that he expects to make an announcement about interoperability with other wiki providers in the next few weeks.  I like PBwiki but will be curious to see what they have up their sleeve that would give confidence to institutional investors.  Mohr Davidow Ventures doesn’t typically invest in consumer facing, web 2.0 type companies.

The enterprise wiki landscape is widely seen as a mess, bereft of reliable, usable and lightweight solutions – perhaps we’ll see someone scoop up this solid service soon. Please hold the jokes about a possible Yahoo! acquisition.

Competitors include Wikispaces, Wikia and others.

I’ve come accross a couple of free Wiki solutions lately and thought I’d post them here. Check out PBWiki and Ben Nolan’s Foopad if you’re looking for a bare bones and free Wiki solution. PBwiki also has very nice privacy features, so you can make a wiki public or private, and turn on or off editing credentials for individuals.
