Probably not going to make it the top of the to-do list but using both Midori and Epiphany browsers (both based on webkit, I think) on Ubuntu 10.10 there are quirks with the forum. I can't add reputation (nothing happens) and I can't edit my posts (I get an 'Invalid Post specified' message). After posting a message, I also get a message telling me to wait 60 seconds before posting another message. Cheers.
