Technology and Communication

I've been working on transferring my blog to wordpress and am wondering now if posterous will make that point moot. If I can interface with all my social networking/media sites via email and web access then I'm wondering how long my blog will live on. It's been struggling of late anyway. I'm looking at the conversation that Steve Rubel is making for the switch from blogging to posterous. Very interesting.

Any thoughts? Can this technology make it easier to interact?
