What does it take for a site to have a good low bandwidth comment interface?
I'm not a technician -- so I'm not sure. But I have noticed that I pretty much always seem to be able to leave comments on Wordpress blogs, for example, whereas I frequently have trouble here and sometimes at Blogspot as well. It helps not to require a login, but Wordpress seems to function okay for me even when it's logging me in.
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
Please post a comment in this thread saying "Hi." You can say more if you want, but just posting "Hi" is good for a guaranteed free point of karma.
