I've just spent HOURS going back through all posts to Grapes 2.0 and giving them labels, as the number is growing so fast it's becoming impossible to keep track. And then, if you can believe it, I went into my template and started dicking with it, to create that lovely label-cloud you see over there in the sidebar. That's right: I buggered about with code and everything. Copying and pasting, admittedly, but still.
If you want to know how to get your own label cloud the instructions are here. And obviously, since I managed to do it, it must be rilly rilly simpule. PS: I made the colours look like the del.icio.us cloud further down on purpose. Not because I don't know how to change them. Ask me about RGB numbers, go on. Ask me anything.
