The one issue I see with putting in a status 410 is essentially eliminating any of the link juice your articles earned. If your articles provide a benefit, people will most likely link to them. The last thing you want to do is take those natural links and throw them in the trash. My advice is to keep an archive of your content unless you have server space limitations. At the very least you should redirect your old content to similar pages on your website.
