why is this shit posted?
Nice first post! Maybe you should explain why you think it's a) shit, and b) shouldn't be posted?
The only flag I can see is that Daniel Monz mentioned 'my post', and the blog links to Wei Gao's post - so something may be up there - but otherwise this seems like useful enough information and isn't particularly spammy or sales-driven.
This shit is the exact kind of shit I want to see on DN (amongst other things). An interesting technical approach to a common design problem presented in a fun way.
