MyWeb is a service provided by Yahoo. It allows you to save any webpage you see for future archiving. Currently in a beta phase that's lasted for at least two and a half years, it can save screencaps of constantly-changing pages, or, perhaps, friendslocked LJ entries. Unfortunately, it does not strip out identifying information. When a post is archived and published using MyWeb, it will clearly identify the user who did the archiving, thus allowing for quick defriending and only minimal lulz.
