Your blog articles will be longer because tweets (microblog messages) are limited to 140 characters - though you can add pictures too.
This means you'll use them for different things.
The main thing is to show your followers that things you do online are connected.

If you want to open one article at a time click on the blog archive in the right column.
Alternatively go to 'search 'we blog' top right - this may give you a choice of several articles.
Click on the title i.e. the name of the post that you want.

On my profile page (what others see) it looks like this:
Others following me on Twitter can now choose to click on the link (if they think it looks interesting) and it will bring them back to my blog.
