You keep bringing up sucking at writing as a core reason there's a poor reception to your ideas. This doesn't seem correct to me, the mechanics of your writing seem fine. A couple things you could do to improve to improve your posts:

• Cut the length. I've noticed this especially with your comments. You can't assume a reader is going to take five minutes to really dig into what you're saying. You need to make your basic case in the first twenty seconds or so, and keep it brisk.
• Inline information. Instead of throwing a bunch of links out there, explain a little of an interesting idea, and then give the reader a link that will help them learn more.
• Your tone. You can be a little heavy handed, which will discourage readers from clicking into your links. Talk less about the people in the conversation (yourself and the audience), and more about your core idea.

Learning these things was very helpful to me, and I hope I can pass that along to you.
