You seem pretty normal. Everything is fun when it's new and exciting. Now that you know everything you need to know (notice I didn't say you're a know it all?) it's not as interesting for you.
I'm a "seasonal" reader - when we're at the S&B there's more time to look at posts. And It's a good way to avoid the "Honey Do" list. (Down to 8 highly-avoidable projects as of right now! :) )
Like, The Biscuit, I go to myposts to see if anyone has had anything interesting to add on whatever the subject was. Then on to new posts that have interesting topics. I don't bother with ATC anymore (didn't know it still exists).
I don't really mind repeats of questions asked and answered (except for the ones obviously posted by trolls asking about guns and toilet paper.)
If/when I have a question, I post it. It's great to get opinions and insights of others. (The snarking I could do without though.)
