From the fact that you have many students ask about research information, does that not show you that SL has relatively high barriers to entry, in the sense that it isn't particularly accessible to the casual user. We have IN FACT used SL but it all seems relatively complex as none of us are really into equivalent "games", ergo it doesn't come naturally to us.
I think even from this information alone we can see that it is relatively "exclusive", we just feel that it lacks any objectives and are trying to understand why, with such poor aesthetics, SL has managed to retain such a high number of users or even if many new members may have joined?
We'd really appreciate any feedback you could give us.
Many thanks,
Matt
