How about "mass sales"? In other words, mass selling of Facebook accounts and other apps to large groups, like high school and university classes, sports teams, hobby groups, companies, associations, non-profits and political groups, etc. The accounts could be "furnished" with some features already installed, like team or corporate logos, etc. Sell 'em all a package deal, all together.
I think you're exactly right about this, Nic. I think when they set AIM up, rightly or wrongly, they intended it to be a sort of "substitute" for private equity deals and venture capital for many firms. If a company isn't interesting or dynamic enough to attract private investors, then they ultimately won't excite anybody on the stock market, even an 'alternative' one like AIM.
