Yes, I've tried google. And it isn't particularly helpful (most of the results are for teachers, rather than for people in between undergrad/grad school). There are many programs I found through fliers that I couldn't find through google first.
Furthermore, google almost never provides the other information that I'm looking for - information that you can really only get through personal experiences. And summer workshops haven't even been discussed in any of the forums I go to, even though there is definitely space for a discussion about them.
