@vvktv,
What exactly is wrong with his (or her, I'm not sure) blog? It works just like this forum does, but in a slightly more user-friendly format.
He posts the LC as a blog post...someone almost always does that here.
The comments section are open to discussion...just like it is here.
Commenters offer ideas or hints...just like they do here.
An answer is usually found (at least that's the hope)...just like an answer is found here.
The only difference is that when an answer is found here, it is in a forum post. This invites people who refuse to read posts to just repeatedly ask for the answer after it has been clearly posted. On his blog, the original post is edited to include the answer. So no one needs to spam the comments section begging for an answer.
