I don't mean to imply that Yahoo is more successful than Google at acquisitions (We know that isn't the case). I just don't think Google is a good benchmark for acquisitions. I think they as good or as bad as Yahoo.

I think Yahoo's problem with acquisitions has been that they are moderately successful initially and then drift away over time. ViaWeb, GeoCities, Musicmatch Jukebox, Konfabulator, delicious and Ludicorp (of Flickr fame) come to mind. Other than Flickr, none of the others are still around, but they weren't disappointments soon after acquisition either.

Konfabulator is still (unfortunately) somewhat still around in the form of Yahoo Widgets for Connected TVs, a platform I have had the misfortune of working with in the past. But I suspect this too will soon be dead as any interest that still exists in this area has already shifted to Google TV.

I sense a theme there: everything they acquired was underwhelming before they acquired it.

Tumblr, on the other hand, has a lot of users that are fully addicted. I can see things turning out differently.

ViaWeb was re-branded Yahoo Stores, and is still alive and, presumably, healthy.

Of a sort. It was rewritten in C++ and Perl (http://people.csail.mit.edu/gregs/ll1-discuss-archive-html/m...), but is still an active product in its new form.

Even GeoCities is actually still around in the form of Yahoo! Small Business. At least from a technology perspective.
