I posted bzplnr as a Rate My Startup, more as a beta program than an acrual launch, and I must say the feedback was terrific - detailed, honest and even a bit brutal, but without exception encouraging. I've made some changes (it's now http://www.fourthirds.com) accordingly and it's slowly starting to gather a few users who are tentatively having a go with it.

Aiming for a re-design and enhanced featureset soon, so I'll be back for more HN honesty!
