I definitely put myself in the 'collector' category, in as much as there's a bunch of people I definitely want pieces by, but I'm the only one who cares out of my friends and I don't really talk about it outside of this community, I just get them done when the opportunities arise.
I'm also planning to/have got a bunch of pieces by my favourite couple of artists and shops and that's unlikely to change unless I move somewhere else in which case I'll likely do the same wherever that is...
