It is interesting to note that Seth, despite being a CMS wizard (or perhaps, because of), uses Blogger for his blog. No point in using a 10-ton pneumatic press when a tackhammer (that someone else cleans and polishes) will do.
I don't know about being a wizard, but going with Blogger was somewhat intentional and calculated. I had gotten up the initiative to start a blog and I didn't want an excuse of fiddling with technology to stand in the way of actually writing. As you can probably tell, I didn't spend a lot of time on the name either. Since making that choice, there were times when I was happy with the decision (like when my friend's self hosted blog was down half the time due to a broken fan in his server), and times when I wished for more than Blogger was able to give. Having a cutting edge blog platform was never enough of a priority for me to invest in an alternative and migrating. So I decided to wait for really nice to have features like categories.
Well, the wait (at least for categories) is about to be over. I just noticed that new Blogger version currently in beta will support tagged categories. There are a bunch of other features that I don't really care about but categories are going to be great. Of course, it is going to take me a little while to upgrade - priorities and all ;)
