Then I think 99% of the posts and pictures will go unnoticed and unread no matter how good the picture is or how witty the riposte on Twitter is. And then the desire goes away.
If I want to post something I can do a blog post like this one or just post a status on Facebook, it just takes a little more effort.
The problem with Instagram and Twitter is that often it's more about getting followers and the way to get followers is to follow people and hope they reciprocate. If you have a big following base then people will hopefully take notice of what you say or take a picture of , although often it's just about what they've had do eat.
I've been very guilty of that, and people aren't interested in what I've had to eat , although people may be interested if I recommend a good restaurant or pub. Anyway I am happy with what I'm doing and when I see things I want to photograph I can take them for my own pleasure , share them on Facebook or Picassa for people to check out.
