Before anyone worries, we're doing really well as a beta. Our stats are really good. This post is looking for ways to improve something we are already doing well, it is not prompted by any concerns on performance so far.
However having said that we do seem to have stagnated over the last month or two, overall activity has been flat or even slightly decreased and while we have a solid level of new content being generated it would be nice to see activity increasing.
Search traffic will naturally increase as we get more quality questions and answers, for example in a search for "should merfolk have vertical tails" we already have the first three links in the results page pointing to worldbuilding. On the other hand though as the site has grown it seems to have got harder for us to get into Hot Network Questions which previously was luring a lot of traffic our way.
Does anyone have any suggestions for ways to improve visibility or activity? Is there anywhere we should be spreading the word? Are there any banners or other similar material that we need?
Or should we just be patient and accept that it will take time to build up the site? The value of the site naturally grows over time as the pool of questions and answers increases and as more people become aware of us. Maybe we just need to give that process time to bear fruit.
