The site places messages from other users directed to you (replies and direct messages) in the sidebar, and offers search in the middle of the screen. Users can save searches and see when new results pop up for that query.

But the compelling feature is the ability to easily administer and switch between multiple Twitter accounts. Some users control their business and personal accounts, or just handle lots of different brands. Tweetvisor is the best browser based solution we’ve seen. It just launched, so don’t be surprised if there are hiccups.

I still say Power Twitter is the best browser interface for Twitter, but if you must deal with multiple accounts, Tweetvisor is for you.

Everyone’s got a “widget strategy.” There are widget marketplaces (see WidgetBox, LabPixies and Wigipedia), widget blogs (see WidgetsLab and Widgetoko). There was a whole conference on widgets earlier this month.

Perhaps this post is just us trying to get it out of our system once and for all – but in all likelihood widgets are here to stay. They provide a lot of functionality to website publishers. Widgets are in their infancy, though, and we’re all still learning how to best use them. After this I promise to never embed 3 widgets in one blog post again.

Blinkx Wall

Audio and video search engine Blinkx now lets website publishers place a wall of search result previews on any site using a widget. The Wall below displays search results for the phrase Net Neutrality. Give it a chance to load, it’s way too slow, hopefully that can be improved. The display is fed by RSS – so its contents will change as new search results become available. It could be over the top, but the size and number of nodes in the wall can be changed – this is the “tiny” version. I’ve used Blinkx feeds in the past to create, for example, a page listing the most recent audio and video news about Zimbabwe. This Blinkx Wall is a much more interesting way to display search results. The down side of this is that search results often include video that’s been removed for copyright reasons – video producers certainly wouldn’t want search driving viewers to their work (albeit on other sites). We found out about this widget at Beet.TV, one of the best places to learn about video online.

Two more widgets, from Google and 30 Boxes, after the fold.

30 Boxed

The always innovative online calendar company 30 Boxes has released a very sharp looking calendar mashup tool that anyone can use to display RSS feeds and iCal data in an embedded calendar. Called 30 Boxed, it displays items organized by date on a calendar. You don’t have to have a 30 Boxes account to use the tool, but this will probably be great promotion for the company’s services.

You can combine multiple RSS feeds, including those for images on sites like Flickr. This could be used to push calendar updates or chronicle events and phenomena. For simplicity’s sake, the example below is displaying a single feed – photos tagged “Facebook” in Flickr.

Searchable Google Map

The Google Maps API team released a new widget this afternoon – a very simple, searchable, embedded map and wizard. In the example below, we started at the location of tomorrow night’s TechCrunch 8 party in NYC. The widget wizard for this one automatically creates a Google Map API Key for your website, but you may want to check the Terms of Service before using this one extensively.

Try some searches in the search box. This took about 2 minutes to add to this post with the help of the Wizard. For a different take on map widgets, see also Platial’s new MapKit.

It’s definitely a shot at the Ajax home page crowd, like the recently funded Netvibes and PageFlakes, as well as Flash home page site Goowy.

Some days I really do think we are back in the nineties. The first thing I thought of when I saw this was long-dead Desktop.com. In this case, though, things may turn out differently. 30 Boxes in an incredibly user-friendly calendar, the kind of thing the Internet masses could take to once they find out about it. Webtop will give those users another reason to try out 30 Boxes.
