I go back and forth on sticking with Posterous or moving back to Wordrpess. Switching back to WordPress could be fun since there are so many plugins, but part of what drew me Posterous was the simplicity and autoposting to other sources like Twitter, Blip, Tumblr, etc. Other times, I think a full move to Twitter combined with other services may work.
One of the reasons I have a blog is to give people an easy way to find my thoughts, videos, podcasts, or whatever in one place. I’ll come up with a solution eventually, but for right now, if you want to find my work, visit http://about.me/iyaz
