Remember the Venice Project? Back in 2006 people were sure this mysterious IPTV solution would ‘kill YouTube’ and even Om Malik wanted an invitation. So, what happened to it? It was released as Joost – a service which offers quite high definition video but still lacks major shows (their offering primarily being a few series of Babylon 5 and Peep Show in the UK) and more often than not has content already available on other sites. They even abandoned their desktop P2P-based approach to taking a more accessible streaming Flash browser video one. Joost definitely is not one of the greatest Web 2.0 services like many expected it to be!

Perhaps you recall ‘Citizendium‘, a wiki encyclopedia which unlike Wikipedia had strict editing controls. The site was co-founded by Wikipedia’s co-founder, Larry Sanger. Despite coverage from major news outlets (from newspapers to tech blogs), Citizendium has failed to ever seem to reach a reasonable size: only 9217 articles in over 2 years. That’s roughly the size of Wikipedia… in Chuvash (a language spoken in a small Russian republic!).

What about coComment? The service in many respects seems to have been usurped by Disqus etc. yet coComment’s aim of unifying fragmented conversation has still gone unachieved. coComment used to be extremely popular, but now I do not know any blogs, nor bloggers, who use it.

Another example is AllPeers. AllPeers was basically a service which allows people to set up ‘private’ P2P networks so friends etc can share files. This was all done through a Firefox plugin. Demand for invites was high, but it has now shut down despite its old popularity!

Web 2.0 was the era of “hype”. This often led to disillusionment and disappointment, but we should not forget the success stories… I know people through this blog who have made a small fortune.
