What To Use helps users find the right tool for the task at hand.
Users can submit tools (this term is used lightly, as we are not merely referring to physical objects) and associate topics and tasks with them. Users can also flag tools that they use as well as follow topics, tasks and other users on the site.
Facebook has been integrated as well so they can simply login via Facebook rather than register a separate unique account. Non-Facebook users can register for a regular account.
