I use etree standards, but I would not want a tracker run in a way that enforced it. There are way too many tapers now that have no idea what that means. And even among etree standards folks, there are variations - putting the source ID in the file name, using tags in a manner that wasn't their design (ie, putting the entire info file in a "lyrics" tag). I've seen some strange things. And while what seems to know how to run a tracker, their rules are a confusing maze of overly controlling requirements. For example, if the officially embedded artwork, released by the artist, is greater than 512 kB, it must be stripped, now making the files different than the officially released version. It may have made sense when a MB or two made a difference, but now? Just plain pedantic to enforce it.
A certain segment of tapers make fun of DIME's rules and here we are talking about trying to get a server set up where there are more rules than currently? And, as much as some may not like DIME's rules or the attitudes of some moderators, they sure as hell know how to run a tracker. Been running for almost 13 years now. I won't seed my stuff there any longer and cringe when I see someone seed one of my recordings there, but I give them credit for a quality tracker.
As far as I'm concerned, other than going down a day or two every few months, I'm happy with bt.etree. The fact that there is very little moderator involvement is a plus to me. No ratio enforcement yet stuff stays seeded for a long time. What more could I ask?
