Okay, so someone asked me why I picked TypePad for blogging. There were two problems I had getting a blog going: 1. Hosting and 2. Content Management. I've got broadband via cable modem at home, but the upstream data rate is questionable for any sort of hosting - plus I've heard that Comcast can be a little touchy about such things. Also, since I don't have a static IP it creates DNS issues having a server located at home. Basically I needed to have someone else host my blog. I have personal webspace through the University and through Mac.com, but both have pretty severe server side configuration restrictions.
The second problem of content management was much less well defined for me. I knew things would start pretty basic, but had potential to become more complex over time, so I wanted something with growth potential. I also have a weakness for attractive design. I looked at Radio from Userland, Blogger from Google, etc. but only Six Apart's products: MoveableType and TypePad impressed me. MoveableType is incredibly versatile, the limits are how creatively you can write perl scripts. TypePad is basically a customizable hosted but pre-configured MoveableType installation.
I seriously considered doing a MoveableType installation on my Blue & White PowerMac G3 and hosting the blog from my house despite the limitations of cable. Ultimately, however, I decided I didn't want to screw around with perl and MT or hosting, so TypePad it was. So far, I'm very impressed - particularly since this product is so young (Beta testing began in Nov 2003).
