High new user retention is obviously desirable for SO and the community in general, has using email to bring new users back been considered? Not only could this help with retention but also with education on the SO ways such as including information on accepting answers, For instance new users could get a summary after so many hours (next day) about their first question(s)? along to lines of:
You first question on SO received 3 answers to date.
The top answers from FOO received X upvotes from the community did this solve your problem?
Others good answers from BAR and FOOBAR also might be useful to you.
Here are some question posted recently that you might find interesting, maybe you could help out with an answer?
Hope to see you back soon
The SO team
I'm not saying we should spam users telling them what to do but an email summary after the first couple of question based on (and tailored by) metrics such as:
- Last time user logged in.
- Number of questions asked (less then 5?).
- New information (comments, answers) on the users posts.
- User accept rate.
Could help bring people back to the site.
If the user accepted an answers the email could contains something along the lines of:
SO are delighted that your question [question title] was resolved!
Any new questions bugging you lately? Maybe you could help out with these..
Maybe if established users stop visting for say month they would recieve an email saying
Look what your missing out on over at SO....
What do you think?
