Hopefully you'll smile when you get a notification about some blessings that were just sent your way.
The blessings and reps aren't necessarily an approval of your content or a reward for how valued you are as a participant. They can be sort of whimsically given. There are members here who write insightful, intelligent, and useful posts but have a relatively small number of blessings and reps, and ones who have billions of each but just lark about the site and don't really contribute much purposeful content to it. For me quality always trumps quantity.
It seems that a lot of it actually has to do with where you post rather than what you post. There are "repaholic" and "blessings exchange" sections here where people play various games and give one another reps and blessings just for participating. The more "power" a user has, the more reps you receive when you are given a rep by him or her, regardless of what you actually wrote. So if you're in an area where people enjoy collecting and giving reps and have billions to their account, just writing a good joke could net you far more reps than an area like this one where people aren't really into the game aspects of the site. There's also a thread where you report the number of reps you've given in the week and are "paid" four million blessings for each one. Two friends here have racked up hundreds of millions of blessings and reps from that thread. One friend said she often doesn't even read the content of posts, but will give blessings to people who have few just to brighten their day. So it's not about merit at all in some cases.
Anyhoo. I've never invested much time in any of the game areas or reported reps for blessings, but I think some of the people who have been so generous in the blessings they've given me did, so in a way I got that benefit. Obviously, you're not the only one who enjoys the reps and blessings since there are whole sections devoted to giving and receiving them. I think it's kind of like racking up points at an arcade and getting tickets that aren't really useful for true prizes but are fun to collect anyway.
I think that when you have gotten a meaningful rep comment or blessing, it can be sort of an accomplishment. There are actually some posts here that have been legitimately helpful to me. I had a science test on Monday and flashed back to a post someone had written here on the subject matter that truly helped me to understand it better. You might have helped someone here, too.
