I only started getting back in to vinyl in a big way around two years ago, with it really ramping up this year (once I discovered discogs).
I'm using discogs to organize my collection. Says I have 423 in there, but I haven't finished cataloguing some of my old records.
My attitude is that I do not want to end up being a hoarder, where I'm just overrun with records that I'll never listen to. I don't "collect" in the sense of buying records only for some other sense of "value" (e.g. this one was released with a wonky label, only a few made!), or rarity, or just for completion sake. I'm looking to have a managable number of well curated records, buying only the records I will listen to (and not for just a song or two, but most of the record has to appeal).
That's why I don't do much crate-digging at all. I don't like hauling vinyl home just to take a chance on it, and then ending up with records I don't listen to. Discogs...and youtube...allow me to listen to lots of tracks from an album before I buy.
But...I have to say I went vinyl crazy for a while, started buying too much, and have nipped it back to a sane number of records...for now...I hope...
