Yeah, I have to agree with this.

I have a long-term client who is a smart guy but is basically a bit averse to learning new technology - he's good with Excel from a previous time in his life, but feels now like his skills are better used elsewhere (which is not an unreasonable position to be in, sometimes). We tried him with Pivotal Tracker, and he did make the effort to use it, somewhat, but it never meshed well with how he wanted to work and he kept doing odd things like creating additional empty tasks as "dividers", which was infuriating. Then we tried him with Jira - he never got anywhere with it; too much UI, too many tabs, too many things to fill in, and the hour-long walkthrough I tried to do was just too much listening.

Finally, entirely independently of me, he started using Trello. He got it immediately, with no assistance, and loves it - he even uses it for non-work things now.
