William Shatner beamed down to social news site Reddit tonight — or at least he claims he did. Plenty of celebrities have appeared on the site, usually as a featured guest of an AMA (“Ask me anything”) session. (President Obama took part in an AMA in August.) Shatner was just dropping in, though, and had some convincing to do. How about a screenshot of his iPhone screen? Will that do it?

Shatner had some trouble comprehending Reddit’s “karma” system. It’s so … illogical.

Those Carrie Fisher fans are everywhere causing trouble.
