Yes, the primary audience are local residents. I would not particularly consider myself an ego-blogger looking for a huge audience, though I suspect I have my moments. And I do occasionally blog on subjects that are not directly related to the area. My suspicion is that I probably am too local and that some extra non-Wandsworth posting would improve the balance and add a bit of flavour.
A good point about the accessibility. I have tried to be as accessible and compliant as possible, but know there are bits that are not fully compliant (the hideously unreliable Google maps, for example, use iframes). But there’s no excuse for not having active and focus stylings – I’ll get that sorted in the next few days.
