Wait 15 minutes then check wikipedia :) Every source in the wiki article is either not linked or an article at ACM. Pay wall is a pity. I wonder if ACM crawl wikipedia looking for articles hosted on other (free) sites and link them to the same ACM hosted article? EDIT: I've now added all the real links I could find. I'll check back in a few weeks to see if they have all been removed.
