I will say that it's hard to do so, even the stock specific thread on SI are kinda dead. I guess doing partnership with other financial websites are the key, just like WSJ with SI.
Hope that INSP will die and scrap SI. Or somehow RB will stop operating. Getting IH on "pesudo stock thread search" on all the software is another key... ie more partnerships. If IH can somehow merge with Stockhouse, the Canadian threads will become a big hit instantly... I can think of tons of stategical move, but I have no idea on the financial health of MarketFusion.
