Yea what this guy said isn't worth people wasting an hour on (I did because I thought there was something good in there =P). Covered most of his points in a previous post, but the main points that were valid (that we already know and some are already in the process of fixing and/or making them better) is: Relays should be better in handling future huge load, better user discovery/search, handling spam, and the usernames UX issue.
