Twine - not all its cracked up to be?

I recently received a beta invite (after a few months waiting) to Twine.

On the face of it, Twine would appears to be an enhanced social bookmarking site.

But what makes it(potentially) significant is Radar Networks claim that Twine is "the first mainstream applications of the Semantic Web, or what is sometimes referred to as Web 3.0." . In a nutshell, what that means is that Twine as an application attempts to automatically read and understand the content submitted to it and relate it to other content in terms of meaning, subjects etc

I think its a little too early to self anoint itself as "mainstream" site/application. While it has a rather impressive number of beta users, the range of content submitted to it is rather limited; much of it related to Artificial Intelligence and various areas related to the semantic web. Then again most, of these social bookmarking sites are dominated by tech content.

Also I think the extent to which Twine is truly a semantic web application is debatable (what exactly a semantic web application is, is also debatable). Right now it just seems to read tags and summaries for certain pages although I do think there is the potential for it to do more as the volume of content on the site increases.

Amidst all that vague negativity though, I admire Twines ambition and I have found it quite enjoyable to be involved in the early days of such an application and witness it evolve
