Obsession with twngan

Another cool new service from Google, Google Scholar (in beta too, as always). A search for my name seems to suggest that right now they are doing fine only on well-indexed databases, for example those by ACM, IEEE, or one of those evil, greedy publishers. This maybe a bit too early to judge anything right now, but if they do rely on other indices to gather information, I can't see why I would use it because

1. the indexing done by ACM is doing exactly the same job, probably would even update faster because they don't rely on Google Scholar; and
   
2. it is important in my field to look for latest workshop papers, which are not showing up in their results.
