The idea of annotating the Web has been around for a long time. It goes back to a failed Web 1.0 startup called Third Voice. Today there are a handful of Web startups (Diigo, Fleck, Stickis, ShiftSpace, TrailFire) that let you mark up any Web page by adding virtual sticky notes or comments in a sidebar. One of these, ActiveWeave/Stickis, had to reboot as BlogRovr and eventually sold itself to BuzzLogic.

Now, a new startup that officially launches today, Reframe It, is trying its hand at the same game. The company has raised $700,000 from AD Gilhart & Co., and it boasts an impressive advisory board which includes Esther Dyson, Henry Louis Gates, Jr., and Howard Rheingold. (Dyson was also an angel investor in ActiveWeave). But it is not clear how Reframe It will distinguish itself from the other Web annotation startups that have so far failed to spark a lot of interest among users.

Reframe It is a browser plug-in for Firefox or Internet Explorer that lets you highlight passages of text on a Web page and add your own comments in a side pane. Comment can be private, public, or visible only to certain groups. Anyone with the Reframe It plug-in can then see those comments in their side pane as they browse the Web. Reframe It also has a Twitter-like social feature that lets you follow other people’s comments, as well as comments within groups. You can follow these comments in an RSS feed, which you can track in your blog reader or other services such as FriendFeed. To help get you started, Reframe It allows you to import your contacts from Gmail, Facebook, and (soon) LinkedIn and other services.

The service itself does a decent job of letting you markup the Web and read other members’ comments in context. The problem, as with all of the similar services that have come before it, is that the chances of coming across a Web page that has Reframe It comments is pretty small. So the side pane (which at least is collapsible) will be pretty useless for most people. The comments also are slow to load. It might appeal to heavy commenters, however.

But even there, disassociating comments from the pages where they appear is not always a good thing. Comments are becoming such an integral part of most Web pages (especially on blogs and media sites) that the best way to ensure the most people will read a comment is to add it directly to the page through each site’s commenting system. ReFrame It comments are only visible to other people who have added Reframe It to their browsers.

That is not to say that there is no value in extracting comments and republishing them as original content. In fact, some comment systems such as Disqus aim to do something similar by treating each commenter as an author and collecting their comments across all sites that use Disqus. Similarly, the ability to comment on links collected in FriendFeed or Facebook help to elevate and highlight the comments themselves. But the reason these discussions are interesting in their own right is because they are occurring among your friends or people you care about. What FriendFeed has shown also is that you don’t need to comment on the Web page itself. All you really need is the link.

We got word last night that Diigo will be releasing version 3.0 of its social bookmarking and webpage annotation service today. The company is calling it its biggest upgrade since 2006, when former TechCrunch writer Marshall Kirkpatrick gushed extravagantly over it.

I’m personally not a daily user of Diigo, even though going back and reading Marshall’s review makes me think I should be. I’ll just have to try v3.0 in full later today. A demonstration video, embedded below, shows an entirely new user interface. We’re also told that the code has been rebuilt and over 100 new features have been added. Social networking has been further developed, too, so you can share your bookmarks with friends and groups more effectively.

Diigo is explicitly pitting itself against Delicious by stating: “in the battle field of social bookmarking 2.0, we believe only delicious and Diigo are still strong players, with Diigo clearly the leader in terms of features and innovations…People who have seen both Diigo 3.0 and delicious 2.0 also think that we are far ahead of delicious 2.0.” Sounds like Diigo’s trying to play David to Yahoo’s Goliath.

Website annotation tool Diigo will officially announce its new WebSlides feature next week.

The new widget is an embeddable player that presents feeds or bookmarks as live web pages in an interactive slideshow format, complete with full page content including links, comments, and ads. The widget can be sent to friends and colleagues or placed on websites, blogs, and social networks. A bit of good news for publishers: every slide view will actually register a page view for the content owner.

WebSlides also enables Diigo users to highlight important sections and annotate pages on the fly with sticky notes. Users can also bookmark, tag, share, and clip content from the pages in WebSlides for future reference in their own Diigo online folders.

To set up a WebSlides presentation, you simply enter a feed or list of bookmarks, add background music or voice narration, and click “Play”.

There is a lot of competition in the website annotation space, but Diigo’s WebSlides is the first slideshow widget to preserve total page content. Combined with Diigo’s research capabilities, WebSlides makes for a great product. The company will be presenting in the TechCrunch40 demo pit next week.
