For those of you who used Etherpad with great success, its "demise" was a big disappointment. Piratepad appeared as a great substitute, but some people were put off by the "Pirate" in the name, and the fact that it's hosted by the Swedish Pirate Party.
However, I recently stumbled across Titanpad, which gives all the same functionality, but without the "pirate" designation. So if you have been giving Etherpad a rest, come back and give it a try as TitanPad.
