Looking at the Area 51 stats, we seem to be floundering in a couple of areas, in particular, questions per day and visits per day. What I have been doing (when I get time):
Advertising the site on my Facebook, Twitter and ResearchGate accounts (the Twitter one has been favourited since).
Advertising specific questions on my Twitter and Facebook accounts (1 has been retweeted and 1 other has been favourited).
Spoken with my University supervisor (I am an Adjunct Lecturer) and we are looking at ways to get the site's name into the University and our affiliated Universities.
Posting (hopefully) insightful questions and answers.
Flagging, editing and and tag-wiki editing.
Attending to the review queue, when necessary
Now, it is not much as I have 4 jobs and work 8-12 hours a day, 7 days a week (and hospital visits chew up the time too). But what else can I do to help?
