I thought you want to know about bitcoin because of the title "What is bitcoin? and the technology behind it" but it's an article. I think the title should be Article About Bitcoin and the technology behind it. My thoughts about this thread is that the title is asking and the content is about an article about bitcoin ready to share.
Yeah me too. The title could be a bit more specific to show that it is for newbies especially to click on it.
The attention span of people this days is not that long, they normally scan the page and click on something that looks interesting for them specifically.
Also another idea is that you could write a resume of it here and paste the link at the bottom of the it so people who want to know more can click on it. That way it's more possible that someone will find your post useful.
