Today brings a new frontrunner in the "stupidest names in a merger" category: Yahoo! just bought del.icio.us.

Good for them. Yahoo did a lot of stupid, irrelevant things after accidentally becoming the biggest, richest portal on the internet. Then Google showed up and suddenly everyone realized that life isn't all stock options and foosball tables in breakrooms.

But Yahoo's recent moves have been very, very smart. I'm not sure whether the video stuff they're pursuing will pay off, but within the web space they've been making all the right decisions — perhaps best evidenced by their acquisition of Flickr. If they really wanted to complete the trifecta, they'd go make the 37signals folks an offer.
