I'm not a fan of liking posts - that's the lazy "I want to be heard but contribute nothing" thing facebook has going on - and I admit I do it, and I'd do it here, and it would be a bad thing.
My wish list would be some optimisation to avoid db locks, a mobile theme, and maybe an app if anything was good enough and not silly money (if not, just a good mobile theme - it makes no odds on 3G anyway). And no app that the user pays for either, that just takes the ****.
I really don't get the desire to be notified when somebody quotes you, why would you care? But done well it needn't have any effect on performance so I'm ambivalent.
