Hi , i think the number of times a post is read can be a little misleading as far as judging interest/numbers goes as i think a lot of people read the most recent posts section . so you get people from all over the world checking out whats going on , often finding good ways of organising/acting based on others experience.
Maybe you could flypost/leaflet your immediate area - pointing people towards the site and your posts , or a coffee shop / picnic meet where ideas can be discussed.Its often a good way for like minded people to meet up as well.
