The main question here to be asked is, what do I want this page for?
What I mean is this, if your market is mainly bloggers or info seeking ppl than you might have www.domainame.com your main page, if it is list building you're after (which in most cases you should) than a squeeze page as a main domain is great than just re-direct them after they have signed in.
one size does not fit all, so you must take all the tools, tactics and techniques to build YOUR strategy
