After a year or so of hosting public lightning talks on Fridays, we're finding that it's no longer necessary for us to continue to do so.  We're happy to say that other groups have introduced lightning talks and are holding them in the evenings (of note: Ann Arbor .NET Developer Group, Detroit Java User Group), so there are plenty of opportunities to join in on these talks.  With summer upon us, schedules (and art fair) make Friday afternoon events challenging anyhow, but stay tuned.  We'll announce a replacement for Friday afternoon lightning talks in the fall.
