I hear you...I have that same problem...many times I put myself in comment only mode because I blast through my allotted vote amount.
If you have trouble finding enough stuff to upvote yourself...
On here I rarely find that to be a problem...there is a ton of quality stuff that people post. It really is amazing. If one isnt finding quality stuff, he or she simply isnt looking.
Or perhaps he or she has a different definition of quality than you do? Or is looking in a different tag category that is so swollen with garbage that hours are wasted without finding things that aren't already hit by curie?
