Why bother with Web 2.0?
Why not?
Instead of listing the many benefits that Web 2.0 applications can bring (which I will go into when looking at particular apps). I think that archivists should show a willingness to give Web 2.0 a try. Many of the applications are free and easy to use so are perfect to experiment with.
Moreover, the opportunities that Web 2.0 technologies offer are not a threat to core professional values, instead they offer a more exciting and dynamic way of engaging with users.
If that hasn't persuaded you, how about this statement, given as the reason for engaging with Web 2.0 at the Brooklyn Museum:
"the era of control is over: you can either stay in the bunker, or you can try and participate. And to not participate is criminal"
