modern day pen pals?

i've been thinking a bit about how jealous i am of all these other bloggers and indie businesses doing their illustration fridays and self portrait tuesdays and swapping and trading and getting real goodies in the mail...i've been trying to devise some sorta group penpal/goodie pal dealio where we get fun stuff in the mail...not tshocke crap, but real live fun stuff...like maybe it needs to be in the form of a treasure hunt kind of thing...where you gotta go find the coolest handmade something or another, and another round could be making some sorta something in a thematic sense that gets sent around, and then for another time, we should send out our favorite songs for when we are in a blue mood...or...i dunno...just brainstorming here...should it be round robin-y, where keep sending the same things...and add on too the package...or take out what we want and keep sending it...or just swap out with one person who's likes and dislikes are similar.........or??????? what do you peeps think? anyone in on this? any interest, thoughts? or should we just adopt an already existing one....like the self portrait tuesday one? or not do anything at all?
