When you look around the internet, one thing that always seems to work good in many communities is something like a newsletter effort. The idea is that for each month, the newsletter would have the best of each section that is available on SOE.
for one thing, it's not that hard of a research effort to retrace the best of any section. A little written creation about that specific best of article or video depending on the section. and a provided link.
Perhaps different sections too other than just the best of. Just an idea I am throwing here because I've seen the benefits of such an effort in other communities (even smaller ones than this) so I believe it may be fun and beneficial. Help concentrate the energies towards constructive directions. :) And as it grows, we could think of different things to add as well.
Let me know what you all think.
