As part of my eternal struggle to organise my life, I’ve started building lists at Tada Lists. I’ve even made some of them public.
(Oh, bit of an inconvenient little bug in the system. I originally linked to my public lists at http://davorg.tadalists.com/lists/public/, but it seems that the site doesn’t like the existance of that final slash – it gives an error message. I’ve fixed the link above.)
