There have been various times in past year or so when a current or recent member of my research group had some excellent and/or interesting professional news -- e.g., a job offer, a grant, a paper accepted/published -- and I have thought "Wouldn't it be great to tell everyone about this?"
Usually I end up mentioning it in an email if I happen to be corresponding with someone no longer in the department, or I tell the good news to current group members when I encounter them in the department.
This is a bit unsatisfying. So, should I set up a group on Facebook or use Twitter?
What are the pros and cons of each? I'd like various members of the group to be able to post their own news, so perhaps Facebook is more versatile that way?
