I don’t mind thread drift either, figuring that it will come back into line before too long, and if it doesn’t then it can be split off into a new thread. Besides, as Malgus said, it can be quite interesting and one can learn new things. Some of the best stuff I’ve read in forums has come this way. If it goes on too long I guess someone could give a reminder.
Bugs Bunny: "I speak softly, but I carry a big stick."
Yosemite Sam: "Oh yeah? Well I speak LOUD! and I carry a BIGGER stick! and I use it, too!" BAM!
