When is the right time to launch?

Over the weekend I saw two tools that recently launched.  One was widbook and the other was gawk.it.  Widbook is social book authoring network.  It lets you write books and share your drafts with fans and friends to get their comments.  It also allows you to discover books on topics that you are interested in.




Gawk.it is a blog comment search engine.  You can search comments that anyone wrote on anyone's blog and jump directly to that comment.  Idea is to easily search old and new conversations and start engaging with the conversation.
