Rafe Needleman at Webware has personal content overload.
And while Rafe is at the cutting edge of this stuff, the proliferation of personal content and services is something of a headache, even for later adopters.
Interoperability is of course the answer: what I want to be able to do is aggregate and republish my feeds where ever I want. So that my friends on Facebook, which I dislike (Facebook, not my friends) can access content I’ve written on Twitter or my blog if I want them to.
There are services which offer this functionality, however, I found Friend feed confusing and it’s one more service to sign up to.
Personally speaking, I use Google Reader as my aggregation point. Despite it’s limitations, it’s open, easy to organise and loads superfast (something which neither Netvibes or iGoogle do) and I guess as the Google apps suite develops, other messaging, publishing and social features will be integrated.
