[Following the Gamasutra relaunch, we're continuing to highlight some of the awesome Expert Blog posts from the relaunched site (there's an expert-specific RSS feed now!), and here's Chris Remo's picks for the best of the last week.]

In our weekly Best of Expert Blogs column, we showcase notable pieces of writing from members of the game development community who maintain Expert Blogs on Gamasutra.

Member Blogs -- also highlighted weekly -- can be maintained by any registered Gamasutra user, while the invitation-only Expert Blogs are written by development professionals with a wealth of experience to share.

We hope that both sections can provide useful and interesting viewpoints on our industry. For more information about the blogs, check out the official posting guidelines.
