I don't care about 99.99% of Twitter posts enough to read them, but I'd certainly not call them "massive" -- in fact, much of my lack of interest in microblog posts comes from them being far too short to convey any ideas of substance.
Consider that you might indeed have a short attention span, and that there might be a lot of insights and concepts that you may be missing out on due to unwillingness to engage with long-form writing.
That's all fine. I am not a fast reader and spent 40 minutes before my spouse entered. I saw I was only at 3 quarters, that's more than where I get at in the average book I read, so still super engaging! Probably already spent the same amount on reading comments.
