I was just thinking the same thing! I started typing a reply out to someone's criticism of this, and it had me think of it this way. I have my own personal stylesheet that I use as a plugin for overriding blog styles (just because I like to read text formatted in a specific way, a lot of blogs aren't very readable IMO). This style of library kinda extends that where the end user can "customize" or make the site look how they want it to (not that it's something people should be considering when building their blogs, but I think its fairly normal for people to have opinions on these things). --- I especially like it for quickly prototyping internal tools/sites at work. A lot of times I want something to look clean but don't have the bandwidth to really customize a lot of stuff. This allows you to write CSS for what you need, but have the overall page styled for you with minimal effort. (Also building your own css templates like this helps teach generic css. I think it's a good skill if anyone is within proximity of the web).
