I post a lot.
I generally try to greet all of the new people on the introduction thread in hopes that even more people join our most-of-the-time happy lounge family. I sometimes wonder why we all dont do that. I post 50-70 times a day. Keep in mind that 3 of the months I have been on this site I was not active.
I like to take part in every thread / conversation. I try and make my posts relevant to the thread I am posting in. I think that we should ALL at least give our opinion once in any thread a lounge member creates. In my opinion (and only my opinion) it is impolite to let someone's thread go by without a single response. That is like a big "we dont care enough to respond" to me.
I do not like it when people call us high posters spammers.

There is a difference between someone who tries to contribute to a thread vs someone who gets on a thread and says haha or +1 for post count. The exception to this would be the few of us that like to toss zingers or one-liners back and forth. *shrug* if you take that away then I think the forum would be a dull dry place.
Keep in mind that some threads actually call for a 1 post reply...
Sometimes the forum moves too slow for me. This is a very small site but is filled with high quality people. I generally post on three sites and this at the moment in tied for first.
