open limping?

I'm playing 6-max now cos the site I'm whoring doesn't seem to have much full-ring action. $10NL.
I played a couple of thousand hands then re-read the stickied posts. Thanks to all who wrote them!

Anyway.
I'm noticing a LOT of open limping going on. I don't like to open-limp unless I'm on the button, actually, even then I don't like it. I tend to raise or fold an unopened pot pre-flop, unless the table is super-aggro and I'm looking for the chance to 3- or 4-bet. Is this a leak? what are people's thoughts on, for example, open-limping with 22-66 UTG+1 when there is loads of pre-flop limping and not much raising going on? or TJs?
Curious...

This has been discussed a bunch daven, if you haven't tried searching I would, it's pretty much a dead horse.

In 6max I think it is generally accepted that you should open raise pairs from all positions as long as you know how to play them post flop.
