A forum doesn't become popular only because of the information it contains, but because we enjoy the interaction and sharing out thoughts and experiences.
By any measure, Early-Retirement. org has to be successful. 56 thousand threads, 1.2 million posts and 28 thousand members.
Driven by questions and common interest subjects, new posts always prompt response... often on subjects and duplicated in earlier threads. This keeps the life in the forum.... and we see that, and it is good.
Many newcomers, (and those of us who haven't read all 1+ million posts) come up with questions, for which we really need answers, which may be technical or need extensive explanation... which have been hashed through... thoroughly.
Our moderators have been excellent using a hands off approach but gently pointing some new posts towards earlier discussions. (lots of tact here)
Mea Culpa... I'm guilty of starting new posts on subjects that have been explored to death...
So... when a question comes to mind, where I need real answers, I resolve to use the search function, to try avoiding the re-invention of the wheel.
Could be a help to newbies, too...
