It happens to lot of people infact about 3 threads exist about it.
Countless of threads exist about it and this will not be the last.
No doubt more threads will surface. People ask questions about things they don't understand in order to get clarification, so once's who don't have that amount of post already reach theirs, they might ask a question about it or use the search button, but it seems people like to ask questions rather than search for already existing answers.
