> Does it even say what the product or service is?Do you really need spoon-feeding that directly?
The whole site is about the product. Much more information about it is literally a click-or-two away. Describing it specifically on that page, given how much information is already around it on directly linked pages, would seem superfluously wordy (even to me, someone who just used “superfluously” instead of “overly”).
> Or is it self-congratulatory spam?
Largely, yes. But no more than so people having anniversary parties are showing off, do you begrudge that sort of thing too?
I much prefer that to a self-aggrandising comment essentially stating “I'm better than them because I wouldn't post something like that” (yes, as some may be wondering, I am self-aware enough to acknowledge the strong touch of hypocrisy in that comment!).
