Okay, here's my problem: Lately, I've been on a smart Streak and am starting to acquire reputation (Thankfully all good).

But here is my Dilemma, when I post something really smart or nice and people give me good rep what should I do? should I give them rep back as a sign of my thankfulness?
or should I just send a pm saying thanks?

I'm really in the dark here, I don't want to be someone who you say I did good I'll give you rep, but I do want to show I'm thankful. I like alot of the people on this board but I'm sorry to say as I don't have alot of time I don't see many threads, only the ones I know I can be of use or will interest me do I go in, so I don't have much of a chance to find posts that are above average and should get rep. I mean most people on here usually post nice stuff ( at least from what I've seen) and I'd like to show that I respect that, but I don't want to go around repping everyone who didn't say something wrong.

any suggestions?

And what kind of post do you give rep to? and what do you consider a worthy post?
