I recently set-up a CevApps Group and a CevApps Sites to manage the roll-out of the new identity and new logo.
Up to now, there are 41 members, 3 contributors. I have no statistics about viewers, but for what I see, it is probably not that many.
Will email be the primary communication system for years ?
To my readers (maybe less than I think) : move to the group of writers and convert 2 from passive to readers.
You can't benefit from others knowledge if you don't contribute yourself.
