Long discussions or posts?

I read the title and first few lines and if I'm interested in the topic or intend to reply I will read the full discussion.

I posted the same discussion recently. Many responders said that if the subject line caught their eye, they would read it, some said that they do not read long discussions. I will read a long discussion if after reading the first few lines I find it interesting. So far, I have found that longer discussions are better because it gives you something to respond to, rather than the one or two liners asking, do you like this or that. I am going to check out your long discussion
