I tried online poker for the first time today

[Bluegrassplayer]

I put twenty dollars onto pokerstars. (don't say I should only have a bankroll of 1 buy in, my debit card has enough for more than 20 as it is and that is essentially my bankroll) I got the 20 up to 100 then dumped it all back on 3 very big suck outs.

Should I be taking my money off the table after I've tripled or doubled up on one table to cut back on variance? How much wider do I need to broaden the hands that I put people on now that I'm playing online? Any just general advice for someone moving from live to online?
