Posting a Diary Entry
Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as
is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.
When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.
If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.
ATTENTION: READ THE RULES.
One diary daily maximum.
Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries
that already cover this topic), though fresh original analysis is always welcome.
Use the "Body" textbox if your diary entry is longer than three paragraphs.
Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.
The term black swan was a Latin expression — its oldest reference is in the poet Juvenal expression that "a good person is as rare as a black swan" ... from Wikipedia.
Author, Nassim Nicholas Taleb, used the Black Swan metaphor in the title of his book "The Black Swan." This is an interesting book, published in 2007, that some say predicted the economic meltdown of the last few years.
For today's Coffee Hour / Open Thread lets talk about improbable events.

In today's Open Thread / Coffee Hour all topics of conversation are welcome. What is for dinner? How are you doing? What is on your mind? If you are new to Street Prophets please join in the conversation in the comments below.
And, what improbable events have you experienced?
It was a common expression in 16th century London as a statement that describes impossibility, deriving from the old world presumption that 'all swans must be white', because all historical records of swans reported that they had white feathers. In that context, a black swan was something that was impossible, or near impossible and could not exist.
