I strongly believe that asking for +rep and asking for people to click the "Thanks" button is tacky. What these individuals don't realize is that, in essence, they are not really sharing - Instead, they are TRADING ("Here's my cool download. Now thank me and give me +rep.").
That is not in the spirit of BHW. If you want to share, share FREELY.
I wrote a post earlier this year about how dumb it is to solicit or "guilt-trip" people into clicking the "Thanks" button. You can check it out below:

I have never been concerned with with getting thank you's or +reps and I have said it many times on the forum. Sure . . . I appreciate each and every thank you and +rep I have received, but if both the Thanks and the Add Rep buttons were removed today, that wouldn't deter me from sharing one single iota. I feel that I have already been paid many times over by the valuable knowledge I have gained from BHW and the great friends I have made here.
