So long Tadalist – Backpack is the new personal organisation widget from 37signals. If you’re as much of a list-junkie as I am then you’ll love it – it’s simple, it’s powerful, and it’s free! It’s in the same category as that really expensive stationary that makes you feel like a better person just by virtue of owning it, let alone using it productively. It’s just immaculately executed and to be honest I’d rather spend all my time making lists with it than doing the things on the lists.
On the other hand, if you’re a team working on a project (oooh, an ARG, say) then I’d highly recommend Basecamp, developed by the same people. On top of it’s awesome usefulness, it’s also hosted for you so it’s totally reliable, perfect for the scatterbrained PM’s out there trying to organise stuff with nasty forum software.
