Meerkat we hardly knew you?

Twitter is cutting off Meerkat’s ability to port people’s social networks over from Twitter to its own service—the so-called social graph. That means when new users come on board, they will no longer be automatically connected to the other people they are already following on Twitter. This comes not long after Twitter purchased a competing live streaming service, Periscope, and just as the South by Southwest festival is getting underway in Austin.
