Speaking for myself (in the deserted forum topic), upon giving it a little thinking I came to the conclusion that the reason I don't hang here that much anymore is that every song, album, bootleg, performance and nuance in the band has already been discussed to death. That's not a bad thing, it's just the way it is. Also, considering that every now and then new members join the forum, discussions will always keep showing up. DT's discography isn't endless, so the 'new' conversation topics somehow got to an end; also taking into account that things have been dead quiet in DT land since the release of the Boston DVD.
I know most bands are like this, but not all fans were used to a Portnoy-ish type of treatment, in which we constantly received goodies, photos, rarities, etc. Now, when DT releases their new album, we will be discussing it for a couple of months; the setlist of their show won't change and we will discuss it for another couple of months and so on, until we reach once again a silent period. It's not a bad thing per se, it's just that DT has become more of a regular band, whereas back then I felt really embraced by the band for being a loyal fan.
My two cents. You may continue your conversation, gentlemen.
