Waiting for the Big Blind
When you sit down at a Hold 'em table, many times you'll have the option of “waiting on the big blind“ to get to you, or you can post a matching big blind and start playing immediately. This a good tell on how patient and online player will be. If he is not patient enough to wait on the big blind to get around to him, he might not be very patient about waiting on good starting hands. Expect him to be a loose player. The opposite holds true for players who do wait on the big blind. Either they are patient or cheap. Both are pretty good qualities to have if you are playing online poker. Cheap players, even when they are not especially skilled will tend to wait on better hands since they are loathe to throw away their bets!
