Fighting my way through the article, looking for some info I read this:<p>...uptake has been slow...
...the idea has gotten little interest from readers...
...The adoption rate is very, very low...
...a tiny percentage of the site’s overall inventory...
...has not been a meaningful driver of revenue...
...the number of paying subscribers hasn’t been huge...<p>Dudes! Instead of repeating the same foggy sentence over and over and over to make an article out of a simple number - how about giving a simple percentage of how many readers have signed up and be done with it?
