Nice saying on marriage.
Me: 10 years of writing many of my own articles on the site
You: It's spammy and useless.
Well, its useless to you, but some other people might be able to use the information or maybe relate to the content.
You and I must be looking at two completely different websites. I see some short articles. I see some long ones. I see some very summarized articles which are called "lead-ins" meaning to bring people back to their own website. I see some in-depth interesting content and I see some bland content that isn't very interesting, as some of the fields some of us work in are not. Considering the 1,800+ authors that have contributed to the website, not everyone is the same.
I appreciate that you took a look, but just because you skimmed a few articles on the front page doesn't mean that the content isn't real. I do filter out the spam from the genuine articles and have tried to keep a very consistent over the years. But you saw what you saw.
As for the topic of this page, "what has your personal website or blog deprived you from?" I think I was able to answer it in the fact that at least 5 hours of my time every weekend are dedicated to answering emails and uploading/processing/scheduling articles to my website. I guess you're going to tell me those people are fake too though they seem pretty legit, even having their company names in their signatures.
