With a WordPress blog you can post by email and also automatically have the blog up date your Facebook wall, So there's 2 for the price of 1. Send the same email to CGOAB and now you're in 3 places. There's also a simple "microblogging" app for the iPhone called trackmytour. It uses Google maps waypoint. Simply take a picture add some text and tags and it tracks your tour on a Google Map. Pretty cool and all this can be done from the iPhone. WordPress also has a pretty good iPhone app.
