Should links to external sites set target=_blank? E.g. I am on www.acme.net and have a link to www.otherplace.net, should that link be:
<a href='http://www.otherplace.net' target='_blank'>otherplace's website</a>
or:
<a href='http://www.otherplace.net'>otherplace's website</a>
I was under the impression that using _blank to sites outside your domain was best practice, but now I am being told otherwise.
