I had a great blab with Masashi (@soycamino), Keizo (@kanji_k) and Dave (@DaveinOsaka) yesterday. It was my first time to Blab. It is not as fun as Periscope but then again Blab is for a different purpose altogether.
One thing I had learned from Dave in the short short time that he was there was that we should judge how long to scope for by the content variety within what we want to show. The more variety the longer you can or should scope. Content could be many things. It could have visual content, verbal content or both. This means you should probably not scope if you have neither visual nor verbal content, unless of course you are out to torture and drive away viewers.
The single keyword, ‘variety’, made complete sense and seems obvious now but it is not always obvious when you are too busy scoping.
