Where do we go from here?

Have you ever thought, 'I am not getting what I need' from my circle of friends or the place where I just hang out or even, dare I say it, at my church? It is good for a moment, but it was just surface talk.
The question is, what makes a 'good' conversation? Is it the subject or is it the people?
Anyone can introduce a subject, but can the people deal with it? Anyone can be there, but what should the subject be?
There are book clubs and there are 'Think Tanks', but is there something in the middle where everyday things can be discussed and everyone walks away 'feeling' nourished?
Church folk talk about "Iron sharpening iron" its a great scripture, but most of the time it is one person dominating the other through debate. Just a quick look at the phrase, it says that both come out of it sharpend. so the feelings that should walk along side it are "though this was a hard conversation, you are still my friend and I have taken a piece of this and added it to my own."

So how does this happen in the busy city and can we be intentional about it?
