I use it as a bookmark. It's a lot easier to type than FIXME or HACK. Like when I have to jump to the top to copy paste a block of code; type 'XXX' at current spot, jump elsewhere and do whatever, then Ctrl-S and 'XXX'. I'm sure someone will point out that there are proper bookmarking commands in their favorite environment but I like not having to remember those, and this works in pretty much any editor/IDE.
