I think this is a great idea and a superb way of getting people looking at some of the best (and slightly older) articles out there.
Here are some suggestions from warhammer39999;
- Posts that you considered special that didn’t receive as much attention as you thought they deserved
- Content that people liked in the past, but haven’t seen recently
- Posts you might have created before your site received much traffic, and now deserve to be re-shown
- Or any content you’re particularly proud of!
P.S, In the process of trawling you archives, why not send some in for the Ultimate Hobby Guide!
