Should I bother making a website?

[Nidhogg Phantom]

Cheers folks! As someone who's finished a fiction manuscript and is delving into the agenting world, the details about an author's platform have me a little kerfuffled. Creating a website is the most recent brain-twister. The idea behind having one would be to show to agents that I'm a serious author who's willing to go a mile or two for some marketing. Problem is, if I were to make one, it would look something like this:
1: A section about my books (of which I have none) 
2: A media section, where one could download author photos, book covers, and find links to media coverage on me (except I have no photos, no books to put a cover on and not a whiff of media coverage for possibly eternity)
3: A mailing list signup to receive news about new releases (even if I have nothing to release and won't have any until an agent picks up my manuscript)
4: A little contact information for fans and others who might wanna contact me (though they have no reason to do so because I have no content that they might be fans of)

There would be some other stuff of course, like an author bio, but you see the problem here, right? Until I have something to market, there's nothing to put on the website. Would an agent be impressed anyway? Or are my energies better spent elsewhere?

Was told to make one by an agent, and I asked the exact same questions. What sort of lame website would I make at this beginning stage? Who would care?

But I was told that an authors website will:

• Have more indepth information about my story, plus pictures that might go with the mood
• Have a better bio than the small blurb of a query.
• Have a blog, where I can demonstrate my ability to write more than one story. The blog seems to be the most important part. Write something. Anything. Show you can be a professional writer by taking the time to do it often.

Being that I'm in a creative industry, I took the opportunity to make a portfolio, as well. Perhaps you have something else you'd like to showcase?
