You know what you're talking about, so I'll agree that you're right, but the simple action of searching titles of submissions on Reddit didn't work. That makes it seem like that there's something wrong with their code or database setup. Reddit's source code is pretty disgusting.
There are tons of sites like reddit. Digg, delicious, Hacker News itself...it's not a good sign that Reddit needs to outsource its search to IndexTank, when literally every other site like it can handle search themselves.
Nice site, just added my blog. Only problem I see is that if it does keep growing and becomes popular, then people could add feeds of irrelevant blogs, and like most social news sites it would turn into a digg/reddit.
Things like Lego Mindstorms help kids move on to the next step - maybe Visual Basic or Python. No one starts off with programming, it's usually WYSIWYG or similar paradigms.
