The whole argument about how HP has scale and all doesn't seem to matter when I see lag on my Touchpad, and even less so when I'm trying to show people how elegant multitasking is. Adding to that, if 'scale' means pushing webOS through every possible distribution channel within your reach, regardless of how laggy or 'not quite there yet' it is, it's still going to result in a cruddy user experience and thus more webOS haters.
this is probably the most unoriginal suggestion, but you could always have a moderately popular site and get money off google ads or selling ad space to local businesses relevant to the site's subject matter?
