Well I think the previous big name one alienated anyone past their mid-teens (mentally at least) between the 'humour' and the amateur bikini girls. I think the "Black c#nts & Brown wings" edition really was the lowlight. We all have the internet so no-ones buying a kite mag to see bikini girls, plus it offsides every girl kiter in the country. Every single edition featuring 57 pages of Ben Wilson probably didn't help the cause either.
By all means local content & riders are great but focus on their riding don't fill page after page with their their likes/dislikes/favourite foods etc.
You can never have too much tech, gear news, reviews, how-to's, trip reports, etc.
If reviewing, try to make them meaningful, we all know that everything has to be positive even if it sucks, but try to at least allow people to read between the lines that something sucks if that's the case. Otherwise your reviews will be pointless.
Good Luck I gave up the kite mag buying habit a long time ago but I'll grab one to support you
