I spend 2-3 hrs here on average, I don't post much ... unless I actually have an opinion or info that I think might add to the thread, (current post exempted).
I work straight nights and browsing these forums keeps me awake (as opposed to watching TV while I wait for the sitter to come by after lunch), and in a lot of cases I learn a bit about euro and aussie cars that don't get much (if any) exposure over here.
Lastly, but definitely not the least, I have broadened my own knowledge on religion, politics and other current world affairs by reading the posts of kickass members such as Misho, Crisis, Henk4 and the list goes on. These are awesome forums and its the members that make it that way, I noticed in the How old am I... thread that many people commented on the overall maturity of these forums, especially noting the young age of many members, this is truly why UCP is the best forum I have ever been a part of.
