At the outset of today's post, let me say that perpetual beta is a pointless Web 2.0 notion (a cop-out) and decidely unhelpful to academics and librarians. Beta-testing. In beta. Not quite finished yet. To be released in full soon. At times, the race that Google scholar seems to be running is against itself - both tortoise and hare. GS has few real competitors, and is cavalier about how it is developing. Why does it do this? you ask...Because it can.
