Om mentioned in the post about VoIP and later on went to differentiate between the consumer VoIP and ‘click-to-call’ VoIP, which usually would be a via an intelligent Web app. Thats one domain where Web2.0 (?) can excel.
I am reminded of the leadership that Sun took years back about ‘Network is the computer’. Personally I see that same leadership driving Web2.0. For me, Web2.0 allows the users to forget about managing applications on their local systems, and leave that on services provided by Web applications and powered by Broadband connections that are fast becoming common.
Think of it as, what a typical home user does on their home PC. Take that outside their home PC and provide for the same application over the web, so it can be accessed from any PC (provided its connected to web). One good example is Meebo. Typical home user (& office user) has one or more IM apps running. Meebo takes this service out of the users PC and provides it over the web. This translates the web from being a source of information & a pipe for data sharing, to a application service provider.
Del-icio-us provided the breakthrough from local to web paradigm, letting users store their bookmarks online.
But for an application to do real justice to the term Web2.0 (and expectations it carries) it needs to have rich graphical user interface. The UI needs to be responsive, placing it apart from regular client-server-client transfers and refresh. AJAX comes in here as one major building block (at the moment) for applications geared towards Web2.0. Meebo again is a wonderful example of it.
I am not sure how Ojos is gonna be implemented, but if it in someway carries over some burden from the users local machine, to the web, it would be wonderful ! I for now suspect that Ojos users need to upload their pictures on to the web to get them tagged, but its too early for me to say anything about it.
Web 2.0 again is a wonderful opportunity for the VC community to revive the bubble. One good thing that comes out of this that the applications start moving towards the web rather than residing on local systems.
