p.p.s. Several people asking in the thread about how to appear on the microblogging sections of Kbin magazines.
As far as I can tell, just include one of the tags that the magazine has listed on its about page, on the right side of the screen. For example to appear on the Apple magazine's microblogging section include #apple or #iphone or one of the other tags on that magazine's list.
Microblogging is a separate tab from Threads, you need a Kbin account to start a new thread.
