Those are the players I played against in my first year here who were some of the best on the site. A lot of them don't play as much, or at all anymore. In all of my games I have only been completely destroyed and owned by two players. Babak in one game, and djbent in another. I've played against most of the current top players and never got thrashed like I did against djbent. Now on the flip side, I've gotten much better since then, and grabbed a 3 way draw in a game both MM and Babak were eliminated in, so I'm not sure my perspective is clear.
I do agree with Zultar in one respect though, many of these players ghost ranking, (ex. PE's all time is 530 or so), is inflated higher then it would be against the competition today. The site is much more mature in stopping solo's. Another large factor is a few years ago not many people understood how to manipulate the GhostRating system as today, so the people that did were able to increase their rating quicker and higher then they would be able too today.
The more recent shift from points fascination over to ghostrating system made more people aware of how it works, and hence people are more cautious making it hard to increase your ranking quickly. And as Zultar said, there are a lot of newer players who are really skilled, everyone he listed, goldfinger0303, Tom bombadil, Zultar, 2ndwhiteline and some others are all excellent players.
I'm not sure the competition is "better" skillwise, but overall, yes the competition makes quick ranking rises harder.
