I like the idea of a private blog if getting the RSS and reading posts was as simple as public. If there are too many hoops just to get notice of and read a single post it will get frustrating.
I hate to see us lose your input but I wonder if simply publishing articles with no comments enabled and having a members-only forum wouldn't be a good compromise. There's something about the immediacy of the response form and the lack of accountability available from anonymity (oh, hypocritical me) that seems to encourage people's awfulness.
And a belated Happy Easter to you too! The fruit cakes being compared to bricks definitely makes my chuckle list ..perhaps some fruity garnish around the display would have added more relevance. It is quite strange how the human mind works, and association is key to avoid possible misyunderstandings like this one! Classic!
