As Pink Elephant quite correctly observed there is mor to Kanban than just the look. However I find the simple card based view, tagged with the status of the card, without the rest, to be extremely for lightweight work, such as blogging and similar.
Working with and developing IT projects, at a number of levels, is what I do for a living, so I do have a bit of practice!
Trello is more than I need for personal use, but is the only useful tool for the job that I have found. I want to get rid of it.
