Since the submitter did not see necessary to add information about "plinky", my hesitant 5-second peek at the unknown URL reveals some type of weird poll/questionnaire site with probably some "social media" scheme.
To be fair Hacker News doesn't allow you to submit a link and write a description. Therefore, any description would have to be posted as a comment which in all likelihood would eventually trickle down to the bottom of the comments.
Submitting a url as he did is no different than a ASK HN: Review my startup.
Looking at the Submit page, there is a spot for the URL and another one for a title. I may certainly be mistaken as I have never used it, but I would think those two fields are just for the described purpose?
I took the plunge and looked around the site. I didnt actually sign up; it sure wasnt anything I wanted. It looks like a way for the creatively challenged to create content for the various social networking sites. The user doesn't even have to come up with a topic; they supply it.
My initial reaction was why not. Web sites are cheap. Throw it out there. See if it works. After all icanhazcheesburger.com became a hit. Then I went into the "about" section. It's run by a suit and it is funded by a couple of VC's and an angel. It has a bunch of employees. No discernible revenue model. I say they have some pretty high barriers to success.
