I recommend being very discerning where you put your "U Comment I Don't" buttons, because you just might scare off some potential commenters. As every one here knows, for each comment I get, I comment about seventeen million, six hundred and fifty three thousand, and one hundred and fifty two times, crashing everyone's web servers with my slightly overbearing love.
Ok, ok! I admit! I do try to comment at least once, but I have followed every link to everyones site each time they've commented. Sometimes a decent comment doesn't pop into my head, and I don't want to leave poop stains anywhere, so if I don't have a decent comment to leave, I don't comment. Usually, I do comment though, almost impulsively and addictively, I need to feel recognized. Need to feel special. Extremely special. Extremely. Something that stops me from commenting sometimes is long articles like this one, because I already have books I plan to read. Occasionally I do read the long articles and comment, but I usually search for a short article. I find that using bold at specific areas of text increases web bearability, because it helps others, especially for long articles.
