An ineffective email conversation

The following blog article is an ineffective conversation that lasted 9 months to order a laptop.   By the time the laptop finally arrived, newer models of the laptop had been released.  It was ineffective because they did not carefully read messages, did not respond to specific requests, did not meet commitments, and failed to quote previous messages to maintain context.  I chose this blog article because it is a perfect example of how a conversation over the internet needs to be well organized in order to save time, money and effort of everyone involved.  This topic fits in our class outline because it talks about effective conversational writing.

Describe a blog post

             1.)What is the title of the post you chose

The title of the post that I chose is called “The Impact of online sales tax.”

2. )What is its permalink URL?

http://cis471.blogspot.com/2011/09/impact-of-online-sales-tax.html.

3.) What tag(s) does it have?

“The Impact of online sales tax” has three tags or labels, called amazon, policy and sales tax.

             4.)    Why did you choose it?

I chose this blog because Amazon does not charge for sales tax as of now in California.   The issue is very important because the extra income from the amazon sales tax could benefit many Americans if collected.   The author suggests using progressive taxes for those that can pay for it and corporations that take advantage of unreasonable loopholes, to help out the poor people.
