Google has a President's Day weekend warm fuzz for anyone publishing their blog's RSS feed with FeedBurner: Google Reader and start pages have just begun reporting successfully to the service. Anyone with a blog that uses FeedBurner, as this one does, should be sure to hit their dashboard this week. Via ProBlogger, where comments suggest a bump of +50% or so -- right around the neighborhood DIA's spiked up -- is fairly typical. Viewed a little bit more broadly, the resulting pie chart also gives a clear indication that Google Reader is fast displacing Bloglines as the dominant RSS aggregator, a potentially informative footnote to last week's RSS how-to.
