It's always frustrating to me when I click on a link in a blog and it replaces the current page instead of opening in a new tab so I can refer back to what I was reading. Did some searching and found what seems the most simple solution for blogger.com sites, this should also work for Wordpress too.
Type out your post and do your links as usual and then click on "Edit HTML"
Now search for the "http" start of the link you entered. This is great if you've entered a few of them because it also highlights each one of these found. So you'll come across your link like the below:
<a href="http://postcardsfromazeroth.blogspot.com/">Postcards From Azoeroth</a> - Rioriel Is Awsome!
What you now need to do is add - target = "_blank" just after the last " in the actual html address. See below:
<a href="http://postcardsfromazeroth.blogspot.com/"target = "_blank">Postcards From Azoeroth</a> - Rioriel Is Awsome!
And then all you need to do is publish the post!
This can be done on all your link pages and anything else you have links on. It is a little annoying if you've got loads you want change but copy-pasting doesn't take ages. You can, if you have lots and lots of these paste them into a word document and do a "Replace and then replace all the /"> with /"target = "_blank"> and then paste it back in though I suggest keeping the word document open till you've checked all the links afterwards that way you can do a "undo" and restore it back if there are other instances of /"> other than associated with links though I've not come across it.
EDIT: P.S. The highlight feature keeps your text background as white in between highlights when you switch it back. To remedy this highlight the text with your mouse and then click on the Tx button to "remove formatting".
Hope this helps oh and go check out Postcards From Azeroth if you get a chance. Amazing stuff!
