You can participate weekly (actually, two opportunities!) in #SocialCafe events. The Twitter Chat starts, and there are 30 mins with just tweets. Then, the Twitter Chat continues for another 30 min (60 min total) while the LIVEStream Hangout starts (video) here on Haaartland (on the event page). You can always join with this link >> https://sw.bcafe.co/join
The Twitter Chat and LIVEStream Hangout proceed simultaneously for 30 minutes.
