I've been using Blogger since 2004. It's a pretty good service, but the neglect of basic features and the problem with spam blogs is a major irritant. If I had the time and inclination, I'd switch to Wordpress.
Today Google trotted out an update to its Blog Search tool, which I've also been using for years. It never was that good, thanks in large part to the huge amounts of spam it indexes. The update looks good, but the underlying spam issue has not been tackled. Until it is, and quality blogs dominate the results, I'm sticking with Techmeme.
