Here are my 2 pennies .. Kim .. I often say that if SL just did what was supposed to do .. It would be great ..but that aside .. . here is where I see the "X"..Any day now there will be more than Bluemars and Twinity both are just as SL, just not as good .. You arrive, you walk around, see things, do some things ... I think what has to be developed and I know some work has been done with this.. Is the ability to control the movement of your Av in a more direct way.. Puppeteer was as I know, and I could be wrong, abandoned.. I think the thing to make SL gap the coming competition would be the ability to move your Av beyond what is available with the current Library of Animations .. and while I am here ..
What always amazes me is how little people know about what they can do here .. An example ..a 300 day plus resident .. She had no idea you can Swim in SL, had no idea you could Sail, had no idea you could drive around the Mainland Road, no idea there were beautiful large seas (that you cant rez a boat but in a few places, but that is another matter) . . So, maybe a way to let people know what they can do here .. and being in Marketing myself I would say that you have to get to a wide audience quickly and there is no better way than traditional television advertising .. The upside would be probably 1000's coming to SL, the downside .. Well back to the top of this long post
more people=more lag=more frustration=more people click and leave .. If SL only did what it was supposed to do reliably it would be great .. BC
