I think, too, that it all depends on what you’re doing with the resume. If you’re posting it online where you’re trying to get an IT job and you don’t care if you land a job writing code, or doing database administration, or helpdesk work, or whatever, then having a resume displaying all those skills (if a person has them) is okay. But if you’re interviewing for a job where all you’ll be doing is pounding out C# code all day in a cubical, listing helpdesk experience etc. is most likely stuff they don’t care to see as it just clutters up the resume.
Anyway, when one person says the site is too busy, I take it with a grain of salt, but when pretty much everybody I talk with thinks it’s too clutters, then I have to step back and reevaluate my position. I'll reduce the clutter soon.
