All of my articles are long, that is just how I do it, I put a lot of information into my articles. One of my articles hit the pop spot with just under 1500 views. However as a reader, if your article contains a lot of scientific information, I want it to be long, I want o get as much information from it as I can so that I know what I am reading has been researched, if it's mostly personal experience, I prefer it be shorter, if it matters that much to you, you should be able to express it in a firm manner, that gets strait to the point. However, that all depends on what you consider a long article. I read a thousand words per minute, so I might be a bad rating for what a long article is.

I think topic does play into it. Most of mine tend to be on the longer side I think because I'm a wordy writer. I find that if it's a good topic you're going to have more to say on it and the length is good. I personally enjoy longer articles to read as well.

I like long and short articles. Some of my favorite sexis articles have been rather long, but I have enjoyed the way the author wrote and all the information they included.

It really depends on the subject (for me).

Short for me. I'm just not a big reader. tl;dr, lol

Depends on the subject sometimes I get bored with it as I am reading it.
