This has probably been around for a while, but I just saw it today. Twitter now makes it easy to embed Twitter posts into a blog.

Simply:

Click on a twitter post so that it expands to show the time of the posting and a hyperlink labeled "details".
Click on the details link.
Click on the 'embed this tweet' link.
Copy the html tab and choose an alignment.

Reviewing videos of user observations I did in Dec. using an iphone 4s, looks great (not in terms of my skill but the clarify of the images)

The great thing about this implementation is that the reader can interact with the tweet, e.g. replying or retweeting the post.
