The first thing you should do is to update your SO|SE profile linking and describing Six to eight; learn to sponsor yourself.
Then try to became the new Jon Skeet (Jon has 156106 views on his profile), ok just kidding here.
I think we can't market our apps here on StackApps, we don't have enough audience and this engine, with limited appysh features, can't be our Apps-place (Check my answers here)
In brief:
StackApp should be improved introducing a well organized stackapp-store section, splitting technical stuff from Apps.
StackApp should be advertised: the first noob to the oldest guru should know the existence of StackApps. Imho StackApps is currently used by a small small niche of Meta aficionados users that is a small niche of the 200K users of just Stack Overflow. Add a Tools tab to the header, place a big banner..whatever you want. I think a small link on the footer and blog posts are just not enough.
I believe that SOFI has not enough resources, time and interests to build an app-store for our apps.
That said, I have two proposals:
- Improve the great StackList with full blown domain, sexy layout and massive ads
- Propose on meta an advertisement bar contest for our Apps
For what it's worth, I've asked a permission for a StackApps sidebar contest on meta:
