If you like to research web apps, one of the original directories of Web 20 apps just got a whole lot better. Go2Web20 just launched a major redesign in beta. It is an information aggregator for Websites and apps, collecting data from as many open sources as possible, akin to what you find at Quarkbase and the more recently launched Dataopedia.

Except that GoWeb20 is much more social. It is linked to the Go2Web20 blog written by co-founder Orli Yakuel (the other founder is Eyal Shahar), and it is integrated with Google Friend Connect. So you can sign in with your Google password and leave comments and rate any app. Go2Web already has a strong community among developers and startups thanks to Yakuel’s blog, and the directory fits nicely with that effort.

The new Go2Web20 presents logos of Websites and applications in an easy-to-read grid. Mouse over any logo for a brief description, or filter by category or tag. (For instance, here are Twitter apps and mobile apps). Once you click through to a profile page (here is one for Boxee), you can read a brief description of the app, see a screenshot, a list of blog mentions, Twitter mentions, Youtube videos about that app, as well as data from our own Crunchbase. Buttons on the side make it easy to share any app profile on Twitter, FreindFeed, Facebook, Delicious, Stumbleupon, or Google Bookmarks.

As members add ratings, the best apps should filter to the front page. Check it out and tell Orli what you think.

The site proved to be so popular that the two have kept working on it, adding new companies and products (there are nearly 800 now). They’ve also changed the user interface substantially and have added Ajax components to the site. If anything, this is a fun site to just click around on and read about startups.

Logos can be sorted by date added or alphabetically. Clicking on a logo brings up basic information at the bottom of the page, and companies can also add their own code (a video, RSS feed, widget, etc.).

The site is also taking advertisers for the first time (we are advertising on the site to support this project). Information on advertising is here.

Orli Yakuel (we find a lot of leads on her blog) and Eyal Shahar designed and built the site. Both live in Tel Aviv, Israel.

Creating something like this is a ton of work. The site is nothing but a reflection of Orli and Eyal’s passion for what’s happening on the web right now…the same passion that is driving the success of this and other blogs dedicated to chronicling this period of web history.
