The tweet that prompted this query was one about "UBM speakers" (which seemed to be an ad for a Leslie clone, when I followed the link). That didn't seem to emerge in any natural way from a normal discussion here, so I presume it was spammed by the guy promoting them. Any spammer could use Mudcat as a conduit for twit-spam the same way.

For the others on Max's list - I can see those threads already. Why would I want to be notified any time somebody posts to them? Who would want to follow such a huge and unselective stream of announcements?

Until the frequency drops to no more than two tweets a day, I'm not following MudcatCafe. The sort of user I like to follow is Anne Feeney, who does about one tweet a week, but when she does one it matters.
