I'm really interested to see the responses to this one! I'm currently working with a brand who sit on the fence between the adult industry and fashion industry. For me, it would be an awful lot easier if they moved their products and overall brand towards the fashion side of things as many websites get put off by the 'suggestive nature' of the site, even though there is no nudity.
So far, my strategy has been to outreach to the leading voices within the adult industry, along with developing relationships with similar brands. So far, there have been a few collaborations, and it's going well, but the scope to this strategy is limited.
In your case, perhaps you could reach out to some of the prominent online players? You could also position your blog to be 'against' the rest of the online gambling world. The latter suggestion is possibly a recipe for disaster with backlash from competitors, but if it gets you noticed for the right reasons, I think you could be on to a winner. It's such a crowded (and spammy) marketplace, I'd suggest you to take Seth Godin's advice in Purple Cow in order to stand out.
I'm really interested to see what other suggestions come from this Q.
PS. Dubs and Kyle both make good suggestions too!
