- RiderOfGiraffes 17y agoI've up-mud both of you, but for some reason you appear to have been down-mud again. No idea if it's real, or just some effect of the voting system, but thanks for your comments. It's interesting to get examples to compare, and the name of the singularity. This is one reason why this is a cool place to participate. EDIT: Someone down-mud this comment, no doubt because they think it's meta-discussion, or doesn't add value, or whatever. I don't care. I'm still going to thank people for doing good things.
- blasdel 17y agoWhat do you think 'mud' is short for?
