Nice boost, Around that time you saw an increase was when Google was updating their algo which now pulls headlines from H1 tags on blog sites. Could very well be the reason why we saw a little bit of a bump as I know many have started using those H1 tags etc over the mark up language. Lots of growth but still so much more to go.

Does it still not make sense to run some type of ad system on Hive itself to generate revenue to pay for server costs etc?
