Quite an interesting service, BccThis creates a sot of layer on top of email, micro-blogging sites and social networks that is meant to provide just anybody with a more comprehensive and (above all) contextualized messaging experience. In practice, if you use this platform you will be allowed to send secret messages to people within any group.
There is nothing “mysterious” about doing so, and such a service can be put to professional uses. Think of it as a tool that lets you make some messages invisible to some recipients and you will hit the nail right on the head.
So far, Gmail and Outlook are the two only email services that are supported. The one micro-messaging platform that is supported is Twitter, and the one mobile phone that is supported (as of the time of writing this) is BlackBerry.
I think we all agree that very often private conversations stem from what is said on public streams. This site will let you keep carrying the dialogue where it started, and keep everything as private as you feel it is reasonable.
