Actually, the loss of the Search function just means that I'll be spending even less time here than before, and that I won't be able to assure the courtesy of a response to anyone who comments on my posts.
This probably isn't any great loss to AR15.com, but if any of the more knowledgable posters decide not to pay up, then the content of the site will suffer.
Yes, visitors to this site can contribute CONTENT even if they don't contribute $'s.
Publishers of technical journals have been faced with the same dilemma: library subscriptions don't cover all the publication costs, so they raise journal prices and publication charges, which forces libraries/authors on fixed budgets to reduce the number of journals they subscribe/submit to, which lowers the publisher's income, which causes them to raise journal prices...
Loss of the search function will also greatly reduce the attractiveness of this site to new or casual visitors; this is a bad policy if you want to hook new users to replace the losses due to normal attrition ("the first one's free little girl...").
I enjoyed lurking and learning by searching the archives for quite a while before I made my first post.
At least that helped me avoid starting off by asking "which is better: the AR15 or the AK-47?"
I suspect that if the Search function isn't restored that you'll see plenty of first posts along these lines in the future.
Cheers.
