2nl - loose as you like, but more nitty that you'd imagine at times
5nl - couple of solid tags but the rest are apeshit loose crazy idiots

as you move from 10nl - 100nl each of the following happens.
1) Understanding of appropriate starting hands increases
2) Understanding of pre-flop basics increases, the further you move up the more detailed these basics (e.g. how should your cutoff steal range compare to your sb steal range?)
3) C-betting appropriately starts to happen, rather than always or never
4) The fish ratio gets worse
5) There are more and more regs
6) positional range variation improves among regs
7) nittiness and aggression increase
8) floating starts to happen
9) intelligent bluffing starts to appear - i.e. a bluff where the actions until that point have been consistent with a strong range
10) semi-bluffing in position
11) 3-betting gets more prevalent (only noticed this from 100nl up though, 50nl and i give 3-bets a lot of respect without big reads)
12) implied odds reduce
13) bet-sizing becomes more important
14) level 1 & 2 thinking creep into people's games
15) people stack off less and less with TP crap kicker
16) people stack off less and less with TPTK
17) pot control with overpairs

basically, as you move up the average/median player gets better, there are more and more regs, and increasingly more players have got where they are by grinding and beating lower stakes.
