Technology What?

It turns out there are writers groups on sites like Linked In.  Who knew.  I started reading posts about what other authors  are doing and realize how little of today’s technology I know.  People talk in initials  and discuss their blog swaps and twitter feeds and pintrest interests, while I struggle with Facebook.   Are these people taking classes one after the other, or does it come to them by osmosis? Are you ever caught up?  Or don’t you expect to be.
