I think it was the first thing they'd killed which had been around for quite a while, still had devoted users, and Google didn't offer a replacement. If you look at the graveyard, the pre-Reader things they killed were things which had flopped (e.g. Buzz), things which were no longer relevant (e.g Gears), acquisitions, and mergers where they had two redundant products (e.g. Google Video).
