So, yeah. Quite the night-vs-day difference between GLBSE with 30-40 stocks that all lost money, and that all together traded for a few tens of BTCs over a lifetime and that all together were worth some tens of ks and that all together made some hundreds a month on one hand and MPEx with its close to over 1mn BTC market cap, with its > 100k monthly traded volume and whopping thousands of BTCs to be distributed to investors each and every month. Quite the night-vs-day difference.
Just to nitpick a tad, there were a couple of non-losing assets on GLBSE (like the ones you mentioned, the passthroughs to MPEx). But your overall point is valid, the percentage of losers on GLBSE was high.
MPEX has now 2 stocks that get traded

. Good job ya'll.
"Promoting" your 2 stock wonder, by constantly dissing others, is not how you sell good stuff. This is how you sell crap.
This really good salesman I know, told me that NEVER ever sell your product by talking shit about your competition. Only liars and scumbags do that.
Maybe this is too old-school for you... I do not care.
Look at how btct.co, litecoinglobal.com, bitfunder.com, cryptostocks.com and so on get their clients. Learn something. Evolve, for fuck sake!

Cheers!
