Comments enabled for TikZ examples

Just a quick note to inform readers that I have enabled comments for the weblog and the TikZ examples. Enabling comments for the examples is an experiment. The goal is to allow users to ask question and post comments directly related to the examples.

Currently all examples have comments enabled. Sooner or later the spam bots will find this site and I may have to close commenting for older entries. I have implemented spam filtering, but sometimes spam slips through. Valid comments are sometimes flagged as spam and put in the moderation queue. If your comment does not appear this is probably the case. I will review the queue as soon as possible.

The design of the comments section still needs some polishing. Providing a comment feed is on my todo-list.
