I don't get the point of waffles. Nearly all posts with that tag are humorous and unnecessary or necessary, constructive, but waffles have nothing to do with them. Also, from their tag wiki:
Waffles are supreme. That is all.
Waffles shall never be burninated, because they stand for all that is lovely and delicious, and without them, MSO would not be lovely (or delicious).
If you didn't know this yet, SE's servers run on waffles. Tons of them, every day, are swallowed up via the disk drives into the servers, where they are converted into webpages like this very one. Waffles are vital to this website.
Seriously, though, it's the fun part of SE that many of us are working hard to create that is what the waffles tag stands for. Although some fun may be inappropriate, the waffles tag is harmless and isn't hurting anyone. So just roll with it- if you don't like waffles, don't worry about it. They don't really like you either.
