Answerbag is a wiki or wiki-like site that often comes up if you do a lot of quirky searches (as I do.) It's free to sign up, and members can post a question on literally any topic in the world, not matter how serious or how frivolous. Other members then scan the questions and, if they know the answer, they answer it. I found Answerbag twice. The first time, I was frustrated by the total lack of leaf wipes in all the shops (having been supplanted by Christmas tat) and was looking for a home-made leaf-wipe formula. The second time I was looking for natural remedies to correct a home hair-colouring experiment gone slightly awry. (I can see you thinking Deborama is really too old for such silliness, and you would be right.) Like most participatory web experiences, Answerbag is growing luxuriously and sprouting widgets, gadgets and special interest groups.
