Many people see online poker as a depersonalized version of the game where it is harder to pick up reads.
It is hard to argue with this point of view.
However, there are many subtle poker tells you can still pick up when playing online that many fail to notice.
By such "tells" I mean that there are many signs online players give off to indicate whether they are recreational players or regulars.
Having this information about an opponent can go a long way toward helping you make better decisions in key pots.
