well tbh i think most of the people who are interested in hon will already following coverage on another site and you wont be able to compete with a hon community site on your own here. but then again everything has to start from somewhere, maybe you should just do a few news post and see
well starcraft is one number bigger than hon. so for someone with an interest in e-sports, sc2 news are relevant, while hon news arent. still i am not sure if it is worth the effort. but as long as there are people willing to do it, its good for esr. but the question was if doing hon coverage would be worth his time, not if it good for esr
I personally don't enjoy hon/dota that much, well in fact i can have some fun, but to me it's far less interesting than quake/sc in the long term, but that's only my opinion anyway. I personally wouldn't mind some HoN coverage aswell. At least it could show me the popularity of the game, which is always interesting to know :).
