L4D2 Versus Guide has 200 favorites and 10k views. Thanks!
It may not have have the highest views compared to other steam guides, but it was one of the first steam guides with 5 stars, earlier than any Dota 2 or TF2 guide (I checked when it first got 5 stars). Thanks for the support :) Hope it stays 5 stars.
