I open and read every one in the "Newest" category and check every now and then on Around the Campfire. Most of the time, I find a topic not interesting to me. I may follow it along, out of curiosity to see if it develops into something I might be able to contribute. But every now and there, there are some posts that are so technical, filled with numbers and technical jargon, I am left scratching my head. Those I never go back to.
I am of the philosophy that the only "dumb" question is the one never asked. If someone takes the time to post something, it's important to them, regardless of how I feel about it, even if it's asked on the wrong forum topic or if it's been asked ten thousand times before. To the poster it's important.
As I've said before on these forums, we are all guests here. We should never forget that.
