SNG's are getting harder. Is it just me or someone else is feeling same?

I guess more professional player are coming in now.

The longer sit and go poker games are around, the more experience players will get with them. There are indeed a lot more hardened poker players online than there were say 5 years ago - and many with lots of experience.

In that regard, the games will get harder and harder over time, due to the increasing numbers of knowledgable players.
