I’m the editor for the HTML/CSS content and I can tell you right now that we don’t have enough of this type of “self promotion”. I would love it if more framework, library, plugin, and tool authors would write honest, down-to-earth articles on their experience building their projects and how those projects can help developers. When the tool is open source, it’s hardly “shameless”. In fact, we pay for these articles just like any others.
Of course, that doesn’t mean we only want promo articles. We aren’t going to publish too many like this, but I don’t think we do enough of these. Anything to help new tools get noticed is more than fine by me.
