Show HN: Tag-based approach to connect programmers who have the same interests

I realise that you might be wanting to gain users to your project, but I do believe that having half your recent submissions being liks to tagmask.com is a bit excessive. I haven't counted, at least 8 times in the past few weeks.<p><a href="http://news.ycombinator.com/submitted?id=pankratiev" rel="nofollow">http://news.ycombinator.com/submitted?id=pankratiev</a>

My concern is that while I program in C, Python, ARM assembler, AWK, Bash and more, I'm not really drawn to articles specifically tagged with those things. I'm drawn to things that transcend any particular language, and are about bigger ideas.<p>I don't see how tagging can work at all.

Why are usernames not allowed uppercase?
