My issue getting the people I like over is that the main subs I use have been pretty mcuh unaffected due to small size. Beyond the huge subs, in the long tail, things tend to get over these little bumps just fine. My fav (and now pretty much only) sub had only one comment I. the previous exodus, and I didn't notice anyone leave. But now, some recruitment may be in order.
I'd have a similar problem. The people I'd love to see over here are pretty hardcore into their subject matters. I don't know if Hubski would have the volume of content that they'd want to see on a consistent basis. I'm actually posting a lot about cars and will post quite a bit about boxing to maybe plant some of those seeds. I don't know how well I'll be able to pull it off.
Yeah, I think for now Hubski will be more of a general interest/dabbling site for most users. What's absolutely wonderful though is that so many people here seem to be very intelligent and insightful, which leads to great discussions. That in my opinion more than makes up for the lack of specialization.
