Did you read the article? There are five links on the bottom to sources other than me. There are three or so links in the post itself leading to other stories I have written recently on the subject. Also, to note, my original head was "It's Time To Face The Reality For Mobile Wallets." It was changed by editorial team consensus so that more people would read it. I wouldn't call it a troll headline, but it does invoke some thought.
Also, to note, The Platform is my opinion and analysis based column for ReadWrite. So yes, it is opinion, as stated in the header for the series on top of the article ("The Platform is a regular column by ReadWrite mobile editor Dan Rowinski and so forth). The column we are referencing was discussing a specific point of news (Square Wallet) and noting an empirical observation on the state of an industry segment that, really, has gone nowhere after years of hype.
And yes, typing and spelling are quality attributes in a writer, I have always found.
Also, I am not the one that submitted to Slashdot. I saw traffic coming in from our Chartbeat and decided to check it out. I lurk Slashdot like I lurk Hacker News, Reddit or Techmeme to see what people are saying and what is being read and discussed. I tend not to submit myself because I think that is a little self serving and the boards tend to frown on that practice. Doesn't mean I won't come in and say a good ole How Do You Do and respond to a commenter that is sure (in their own mind), that I will never see the attack on me.
