My posts come in waves as well. I can post a couple of times a day here but then I could go a week without posting. I read a lot of things and when I post, I always try my best to add something. I post often on a site called GameFAQS but I have been going there for over ten years, so it's pretty much a daily website for me. My posting on Reddit has gone down in the past couple of months but it was never that great to begin with.
I've been active on GameFAQS since 2004...it's probably likely we've run into each other over there.
Lately nothing much but a little Crazy Taxi for the PS2. I'm not much of a gamer these days. I'm too lazy to really catch up on the current generation. I first got into Gamefaqs in 2004 because I was looking for FAQS for the game, Way of the Samurai for the PS2. One of my favorite games of all time that I still play to this day because it's short but fun.
I agree, I simply don't have the time to comment each day. It requires a lot of effort, that is, forming an opinion that I know will be scrutinized and read by many others. I want it to stand on its own. And then heaven forbid I comment on something controversial -- because I get in heated debates and the next thing I know https://xkcd.com/386/ . But yea, I find that I comment in waves as well.
