I see a trend on the forums and groups. A newcomer or even a oldtimer will see a piece of "vital OMG everbody needs to know this" information and it turns out that it is a couple of months old. It has already been discussed to the point of making people sick.
Take The Blair Holt HR45 bill that keeps popping up as if its the latest attack on the 2nd Ammendment. Now for those that dont know, HR45 is a truly heinous piece of work that would mandate a National Firearms License and criminalize private sales. It would be an unmitigated disaster for all gun enthusiasts.
That and other things that have been beaten into the ground discussed six ways to sunday, keep getting regurgitated by people too lazy to do a search and read the copious amount of messages referencing said topic.
All I am saying i guess is before you post something on a list, check the date and if it is more than a month old, check the archives. It is very well possible that another supergenious found the same article and posted it 3 weeks ago.
