Here is the marketing website behind it: http://dotshabaka.com/

The controller of the root servers controls the entire namespace. Size of the namespace doesn't really matter. Too bad alternate roots never took hold. Nor has any distributed DNS infrastructure gained any acceptance.

.onion on TOR is the largest non-ICANN top level domain. Anyone know how large .onion is?

In addition to SPF and DKIM, you should also publish DMARC records for your sending domain(s). This way, you can receive failure reports from the major providers that support DMARC.

(DMARC is a DNS TXT record just like SPF, but you list a 'mailto' URI to receive failure and aggregate reports of problem messages.)

That's a bummer that the bi-directional communication does not help with your filtering.

However, asking the user to add your address to their address book may help.

You may also consider dividing your list up with multiple sender/receiver pairs. Subscriber A would get the email from your Sender A, and reply to her. Subscriber B would get the email from your Sender B, and reply to him. At least total counts from Sender A would be lower than a single Sender.

I'm assuming you are also using SPF (v1 and v2) and DKIM correctly.

If I was in the newsletter sending game, I suppose I would try Constant Contact and Mail Chimp and others like that, to see what they do (they probably all recommend the privacy eroding features, but you might learn some tricks).

I think your opt-back-in-every-N-messages is a good idea.

Re-opting in could be done via replying to the email. This would establish a "communication" between the recipient and the sender. It should help against mis-qualifying other messages from the same sender as "spam" if there is a thread.

For example, Thunderbird's junk filtering allows you to whitelist your addressbook. Thus, these users should be encouraged to add his sender(s) to their addressbook. Replying to a few messages might do this (depending on client and settings).

The point is most people who receive the proxy list by email cannot simply view the website or RSS feed showing proxies.

To pretend to be legit, Iran should start a deep space program. Then use the Pu-239 method to get their "desired" Pu-238.

Skip uranium enrichment and go right for plutonium!

Exactly. It's quite difficult to walk or ride a horse while very ill. But lying on the floor on a steam ship or train car will spread the illness around.

Or sick people didn't travel. Or the long-distance traveler stopped traveling after they became ill. Or a horse drawn cart didn't hold as many rats as ships or trains.

It would be neat to see a visualization of the spread of various diseases in our known history.

No, lots of people complained, they just didn't have any choice. A minor change to Windows vs a major change with a new operating system. However, if Ubuntu ships with a new desktop environment like Unity, Linux users have a choice -- change the distribution but not the full OS.

I do agree that:

One size does not fit all.

A growing minority are turning their wide screen monitors on their side, enabling a large vertical space. With the wasted sidebar on the story detail page, all of the comments are squished into a narrow column. This results in much more scrolling, even on a vertical monitor!

At least let me resize the main comment column so I can make it wider or narrower!

When reading product (and book) reviews, I read all of the 1-2 star reviews first. I sense more honesty in criticism than praise.

If you also use Certificate Patrol, at least you'll know when you've been MITM'd.
