web 2.0 bubble Does this mark the beginning of the end for the Web 2.0 party ? In a short span of three days, at least two web based PowerPoint clones have decided to shut down their businesses completely.

Slideaware.com, a PowerPoint hosting service that let you deliver presentations live, sent an email to all existing clients saying that they are discontinuing the service due to a "shift in business plans."

Another service that’s closing shop is Spresent.com. This was actually a very impressive web based alternative to PowerPoint that failed to achieve critical mass.

They are now closing the service according to this email – "Our data center hosting partner is going down. We are trying to migrate Spresent from the partner, but it could take few weeks. We will try to keep Spresent.com site up, but can’t guarantee."

In case you have put PowerPoint presentation slides on any of these sites, it’s time that you download all the material on the desktop and identify a replacement service – maybe Google Docs Presentations is a good choice. Picture: Flickr
