I also hate that question and the 'how are you'.  Always answer with "Fine".  "What have you been up to?"  "Not much".  Same questions, same answers.  A few people have gone a little further and would say, "I bet you spent a lot of time with your grandkids."  Answer, "Not really."  
It's frustrating.  I would love to have a little deeper relationship, but how can I expect it to go any deeper if I don't give answers that they can go further with?  I complain about the lack of deep conversation going past the 'how are you' and weather talk and I know I don't help things, but what I don't know is how to change that.  I know the 'how are you' statement is not a real question, it's a greeting.  You return the greeting by saying "Fine.  Then it's over.  Then I stand there, like "That's it???"  
Sometimes the reason I post some things I've done is to, hopefully, give someone something to start a conversation with, but it doesn't.  For example, I post a picture of the macramé curtains I made my daughter.  Friends may comment on the post, but I always hope when they see me they might say something like, "Oh, those curtains were really cute."  Then I'd come back with, "Thanks, I enjoy doing macramé, along with other crafts."  And the conversation would continue.  But it doesn't happen.  
One lady from church has goats and posts a lot bout her goats, and I have actually tried to start a conversation with her by mentioning the goats (it's the only thing I know about her).  But it doesn't work.  I know I'm just not doing something right.  If it were one or two people I'd say it was them but when it's everyone I know it's me.
