I agree. Too many people have a hangup with similar threads. Who cares? If you don't like it, don't read it!
Like most posters, if I post in a thread, I like to go back later and see if my post had any responses. When I see that a thread has like 50 pages, I don't bother. Who wants to read thru all that crap?!
Then there are those that point out that you should use the search function. Depending on the subject matter, the search also can return dozens of related posts. Again, who wants to look thru all of them to see if your point has already been made?
