I recently realized there are many New Orleans bloggers I haven't met. There are many more who although we have been in the same room or on the same parade route I only know by sight. I know a few by name and some of them I suspect don't know me. That's not too important but a sense of community is definitely fostered by personal contact.
For about 20 years I have been a part of a software community spread across the world. I have come to know most of the members on-line fairly well but had only met a few, until several years ago when we started having annual meetings. In the nolablogosphere there is a lot more face to face interaction, but a great many people I read regularly remain a mystery to me.
I hope everyone will make GD III.
