addendum
Forgot to mention what I’ve never liked about revstreaming: people tucking mini-advertisements every time they correspond with anyone. Some people are elegant and give real and useful information, or give information in a form that they are experts in. But some other people—totally ham-handed! I’d like to think I’m one of the former when I frequently update my blog, http://infrarad2019.tumblr.com, with cogent and interesting analysis on current socio-ludic trends.
