I am interpreting this question to mean "How is posting this link different then posting a new topic on HN with the same text?" (Please stop me if I have simply misinterpreted a snarky remark about the value of my comment. ;)
I wasn't intending to address that distinction in my comment, but the distinction is important because additional traffic to your website has the potential to benefit you far more than posting "a long block of text" on HN does. This is why most low quality submissions come in the form of links instead of text submissions: because the submitter wants readers to visit their website for nefarious sundries.
The point I was trying to make, which applies equally to submitted links and printed text, is that they should be of higher quality than this submission. To me this submission feels like its raison d'etre is to serve the submitter, and does very little in way of sparking interesting or meaningful discussion for the HC community.
To be more specific, it fits into the mold of the variety of submissions that I find to consistently be of the lowest quality: short (and often unedited) posts submitted by their own authors. When I joined the HN, posts of this kind were virtually unheard of, but recently they have become rather common. A simple test for these kinds of submissions is "If someone else found this entry, would they submit it to Hacker News?"
I have to apologize though, my comments here are really directed at an undesirable trend, of which your submission is only one example, and not an egregious one at that. So, I hope you don't put too much weight into my critique.
