Just to add my tupence i'd like to say that I kind of agree with what vbangle said in post 703 with regards to this thread. The words 'spamming' and 'broken record' have certainly crossed my mind numerous times in the past.
What's with constantly spamming in consecutive posts about a blog that's not even a part of this forum? Why not just stick to sending PMs to people that you think might be interested and leave it at that?
The demands that people comment in your blog or get culled is also over the top and totally unnecessary IMO. I agree 100% with what Harmy and Dark_Jedi said about this, you shouldn't be trying to force people to comment, that's just counterproductive.
Having my own SW project that I'm working on here, I can sympathise and understand perfectly you wanting more feedback from people, I certainly like hearing back from people, it helps keep me motivated, but forcing the issue doesn't help anyone and just breeds resentment IMO.
Like Dark_Jedi said, I think you should just relax and do the project for yourself more than anything, not for the attention or approval of others. When you post new progress in your blog, I'm sure that people will post their thoughts without you forcing their hand.
