The last time we did an IRL (in real life) promotional event for TCS.SE was at FOCS 2010. I don't unfortunately have any data on whether that event worked to draw more people in. We also had the SIGACT News article in the latest issue.
FCRC is coming up, and STOC/CCC/EC/PLDI/PODC/SPAA will be there.
What kinds of promotional events might we carry out at FCRC ? In your answer, please clarify also if you plan to attend, and in what capacity you'd be willing to help with execution of your suggestion.
Also, to help with brainstorming, it might be useful to separate out
- activities that help with spreading word about the site
- activities that help increase participation from established researchers as well
- new activities that could become regular occurrences at major conference events.
