Your account seems newish, so I'm not sure how familiar you are with HN as a community. But we generally value signal to noise ratio pretty highly here, it's semi-bad form to repeat yourself in multiple comments, and it's very bad form to say things like 'thanks for your support'. That's more for reddit than it is HN.

No, that's not correct.
Empty comments can be ok if they're positive. There's nothing wrong with submitting a comment saying just "Thanks." What we especially discourage are comments that are empty and negative—comments that are mere name-calling.
I'm familiar with HN. It's just that this blog post was written by me, so I want to listen and respond to the feedback the community has to offer. Most of what got SourceForge in a bad situation in the first place were complaints falling on deaf ears of the previous owners. Improving SourceForge is very important to me.
