In case you are a Scribe and missed the boat on this one, two WoW Economy bloggers are reporting that glyphs are selling so fast that they are running out of supplies to make them. In other words, start selling glyphs NOW. I don't know if they will continue to sell throughout the weekend, but given the server stability on Bleeding Hollow, I'd say yes.

One more side note on this. The Goblin is saying that his ink supplies are running out. This means that the market for herbs may be affected by the glyph market. If you're an herbalist, check prices and supply and if things look good, start farming. I'll be investigating this further when I get home tonight.
