Typography is important.
And should remain important for the goodness of all graphic design (in which type is utilized, of course).
Take note of these…err…notes.

And DEFINITELY these mentioned by Craig:
• Don’t combine two sans serif or two serif families together in a single layout. Helvetica and Univers will clash if combined. So will Centaur and Bodoni.
• A primary rule of thumb is that opposites attract. Combining a well-designed sans serif with a serif face will nearly always create a good and compatible pair.
• And then, avoid excess. Two over-the-top typefaces will look like a collision. A more decorative display face should be paired with a quiet, neutral and readable text face.
