There were no particular annoyances, there was simply no compelling value. I could have hacked together a cron job and web site to send out a "what did you get done today" notification URL to a set of "enter your dones" pages, which would have been collated into a "digest" and I would have achieve the same value. It would have been fugly and lacked slickness, but the collated report would have been of comparable value.
I was hoping for more in terms of rolling up reports, helping me create dashboard reports, etc.
I know this isn't exactly an easy problem, but....
