Flock is a popular cloud-based productivity software with a focus on sharing ideas. It is similar to Trello, only it focuses more on teams/groups as opposed to individuals. Flock allows for posting notes, files or videos and can have comments associated with those notes and uploads (comments are saved!). You also have the ability to chat within a project.

We have multiple teams working separately, and Flock is the one place we can all communicate and coordinate together. It is extremely handy to collaborate with clients and keep all the important parties in the loop.
