For the last few days, many legitimate comments are being mistakenly caught as spam by Typepad's automated filter and being quarantined in a spam folder. I have written to Typepad about this and they have replied saying:
We're moving to a new anti-spam service and in the process, you may see some issues with the current anti-spam features. We're aware of those issues and we're working as quickly as possible to get everything running smoothly. We apologize for any inconvenience in the meantime.
In the meantime, I will be checking the spam folder as often as I can and publishing any legitimate comments I find there. So, if you leave a comment and don't see it appear immediately, please be patient. I will get to it eventually.
Sorry about this and thanks for your patience.
