I agree, I am an "older" owner and I find many of the threads incredibly childish. Some of these posters must be about 17.
OTOH, there are some very knowledgible and helpful posters on here who contribute a lot of good info (when they actually do post).
I try and just skip threads that are obvously "bling" in content.
