Do you actually think the problem here is informational asymmetry? Seems to be a supply/demand problem more than anything. Not enough housing. Not enough qualified summer interns. I don't see how a few blog posts will help anyone...
I learned computer science a lot later than many of my peers, I stumbled around a lot in the startup world before being able to intern at one of the more well-known companies in the valley- this was only after I had learned many lessons and been rejected or not even contacted by many companies because I didn't know how to present myself in a format that made recruiters want to contact me.
Any resource that helps potential interns to learn more about recruiting in the valley- from finding an internship to choosing an internship- is a good one.
