I noticed that for a period of months, the "random article" link would return the same page for me, every time I clicked it. It would stay that way for a few minutes, then change to a different article. Apparently I was the only one who got this issue (although it wasn't browser, OS, or ISP-related, so
). But on June 8th it started working again.
Personally I love this feature. It's my home page.
