I didn't really get into MLP until Season 1 was over. The hype was just starting to flood FA to the point where you couldn't go anywhere without it being there to some degree, and thanks to Youtube, I could catch up without a problem. Yup, first episode was, ok. Then the second caught my attention. By the third I was hooked, badly. Fan made music was also exploding and I eagerly dived into the fray, collecting quite a lot that I still have in my expansive playlists. However, while the fire has died down for the TV episodes (I still watch every one), my vice, my addiction... is fanfiction. Oh, fimfic has me hooked good. I find myself reading during both breaks and lunch at work every time. It's not to the point I've tried writing my own, although I have to admit I mentally entertain a silly tale involving ponies and my own creation (not Morphy) that may or may not ever get written down.
One thing that I still do, but is now infested with technocolor ponies, is my own foolish generosity before Rarity made it an Element. I'll buy a number of those McD's pony toys, in addition to the normal boatload of giant pixie stixs, and give those out at conventions. MFM was also rife with badges for made up conventions (Floorcon) featuring silly pony vectors and names to go with them. I still want to make bumper stickers but finding vectors that're "just right" for what I need is proving difficult to the extreme. I had found a [Vote for Fluttershy in 2012] vector on FA and made a bunch to hand out at the MFM Brony meet in 2011. I still have it on my own car but it's eroded to a blank space since then.
