What the heck is it supposed to do?

That's a serious question. I scrolled all the way to the bottom, clicked on About Jellfi, read a bit about the founders, and then finally noticed that:

"Jellifi matches both professional and casual event planners to the best and most unique local talent for flawless and fun events without the stress."

That (preferably with fewer adjectives) needs to be the first thing I (and anyone else) see, IMO. Without it the service seems all style no substance.

(Granted this may not be as much of a problem with promoters and artists than it is with a 38 year old programmer that lives in insurance.)
