Google is showing more signs of Yahoo envy, as if Froogle wasn't enough, with the purchase of Blogger, or Pyra Networks as the company behind Blogger is known.

Exactly which part of Google this ties into is not that easy to say: Weblogs are similar to threaded dialog (so groups.google.com comes to mind), they are mostly commentary on news of some kind (i.e. news themselves and they are of course simply webpages. It seems most likely to be the news angle and aggregation that will get play as a valuable new source of information on the web. Consistently applying pagerank or collaborative filtering methods to trackbacks and such would be a valuable addition to the blogosphere and if Google maintain their "you don't have to be evil" approach and drive open standards for indexable metadata on weblogs instead of a proprietary Blogger standard, that would be just great.
Alternatively, as a way to build community around Googles own news and search pages (The Google cache is of course a favourite source of permalinks to off-blog resources) this move is also much more meaningful than some kind of my.google.com idea...

If it's not that, it looks a little too much like buying simply a valuable community of home page builders, used to paying for premium service, even if the homepages are of a modern more meaningful kind than the usual Geocities "Hello World" page of the Mahir kind.
