It's a general thing with ALL "web stuff" related forum and sites, one forum I admin at I gets about four posts a day now, and I delete three of those as spam, two or three years ago fifty to a hundred per day was usual. (webmasterground.com)
webmaster-talk.com was getting two - three hundred posts every day and dropped off to twenty or thirty in the space of a couple of days
A lot of is the evolution of the Internet;
bulletin boards gave way to discussion forum and simply died off.
Now discussion forums are giving way to 'blogs' and 'social' media.
Eventually blogs and social media will dies off in favour of the next trend.
Nobody is looking for "Page Kits" anymore they want Wordpress or Joomla! templates and rather than the footer links 'hurting', ninety percent of them probably don't exist any more.
So long, and thanks for all the fish.
