Trello is a great product. Its great that you find it useful and worth paying for. But you lost me right here..
>it’s paid and it won’t disappear overnight.
Thats a gross simplification. Perhaps your company paying for trello, and you blogging about it, makes it a little bit more likely that Trello will stick around and will "succeed". But it certainly does not do much to _guarantee_ that they will hang around for however long you want to use it. Much larger paid-for services have disappeared. The best that they can guarantee you is that they will try to make your data available to you in some form if they ever go away.
