It's interesting noticing some of the posts on the archive thread, coupled with a more recent one (can't remember the title) asking what got members in to the hobby in the first place.
If memory serves correctly, nearly all played with plastics as a kid, tried to grow up in their teens, then reverted back to the big kid again later on in life, only this time, with the income to afford the likes of painted metal K&C, HB, NMA, Figarti, Britains etc.
My opinion is that the longer term 'survival' of this hobby means hook 'em whilst they're young with affordable / disposable, but reasonable plastic, let them do their teenage 'thang' and you've got a ready made market when they're in their 30's, with kids of their own and remaniscing about child hood days gone by.
Whether the likes of 21st C and FOV today will be sufficient to bring in the collectors later on in life remains to be seen.
But,
having the stuff readily avaiable for kids to see and harrass parents is a must.
Having links on www is great, but most kids (hopefully) haven't got a credit card to on-line shop. And with the average kid's attention span being a little less than a goldfish, I'm not sure how effective this would be on it's own.
Cheap and good quality plastic figures, attractively packaged need to be on the toy ailes at Wal Mart / Asda etc and on the shelves at Toys-R-Us. It seems to work fine for 21st C. Stick some larger packs of unpainted plastic next to them and bingo!
Of course I never did business studies or marketing at school / college and I could be talking tripe, but those are my thoughts on how the hobby can survive.
