Tweet using web writing principles

In work we have really started to investigate the opportunities twitter can provide as a tool for driving additional traffic to our content.
It has got me thinking... has twitter created a new behavioural method of reading online? or is this a opportunity to capitalise on a opportunity to create tweets that stand out from the crowd?

Earlier in 2009 I recall reading a study by Jakob Nielson on how we only read the first 11 characters in a list online. This got me thinking about the tweets from the people follow in our twitter dashboards, how many do I actually read?
It’s true, some tweets just blur into one another, and some real golden insight or opinion could be missed.
We also read these pages in an F shaped pattern, so as times goes on, these will appear further and further down the page, and less likely to be read unless they are written in a way which grabs their attention.
So in a congested world of communication.. how do you make yourself heard?
Tight CTAs
Unlike when writing for web pages, we can’t control what content surrounds our call to action (effectively our tweet among 100's of others), so not only do we have to optimise these to fit within the 140 characters, but they have to stand out from the crowd.
Short URLs
Tinyurl, bit.ly, tr.im etc are driving millions of links each day through to content linked from twitter, but the format with their random number/letter collections doesn’t adhere to the practices of good hyper-linking text. Remember, your followers are scanning your tweets, so ‘http://tr.im/dbuxa’ means very little to them.
Having your URL link relating to your tweet could be the most powerful devices that attracts followers eyes to your tweet (i.e. http://doiop.com/webmanagerinlondon)  Have a look at using doiop.com to links with a descriptive keyword following the / for free.
Cant bold? Capitalise
When web writing, if we aren’t hyperlinking, we can use bold to draw the eye to a piece of copy.
We can’t bold in twitter, but we can capitalise without ‘shouting’. My recommendation would be to use this on place names. For instance:

MANCHESTER (April 28) Visit our stand 21B at ACT 2010 Conference to meet an Olympian. More at http://ltsbcm.com/LloydsACT10

In conclusion
Twitter has allowed for the masses to start producing content for the web, and along with this, standards slip.
I don't feel twitter and similar tools will change the way we read dramatically, if anything it will further enhance our scanning/discarding of content if it doesn't grab us straight away.
