For such a small announcement, you could just have posted this on the main page of the game profile. All your subscribers would still know about it. Or ideally, you could have explained briefly what kind of features you game has, how are they relevant to your game, or which ones you think make it stand out more. I don't know, man, something more creative than a one-line blog...
One-line blogs are not cool. They're boring. They push other people's blogs down who have as much right as you to talk about their games. And they make you look like you're just hogging for attention. Please, don't do it again.
I can understand your frustration with one-line blogs alterego and while I agree it could have been posted on the main game page, it would not be seen by others who have yet to subscribe or have not heard anything about the game.
I can asure you that I have no intentions of hogging the blog advertising slot on the main page, if you look at my previous blog there is only a few short sentences there as I never force gamers to read endless amounts of text but send them a link to a more informative page.
