I have a few pages which have been very popular over the years with teenagers, each with tens of thousands of user comments. We've always moderated our comments for spam, but not mis-spellings and bad grammar, and these comments contain a lot of mis-spellings and bad grammar.
These pages have lost a lot of traffic due to Panda (the entire 150,000 page site has lost a lot of traffic due to Panda) and I'm wondering if I should implement comments through AJAX. As far as I can tell, Google won't index text that isn't in the initial page HTML, and AJAX will load the comments after the initial page load.
The comment sections on each page have become like little communities where visitors help each other and I personally feel like they are the most important parts of my website, so I don't want to do away with the comments altogether.
Any thoughts on this? Would this be a waste of time?
