Strengths
Without a doubt, Mitch's blog has more strengths than weaknesses, so it is difficult to pinpoint or enumerate them all. Off the bat, though, Mitch is adept at identifying emerging trends, and putting them into a light and/or context that most people don't see coming until they are already old news. In this way, digesting Mitch's thoughts on a regular basis will definitely enrich your perspective on marketing.

An additional strong point of the Twist Image Blog is Mitch's podcast Six Pixels of Separation. Mitch definitely has a kind of talk radio flare that most podcasters lack. More importantly, however, he really makes an effort to integrate the conversation into every podcast. There's an audio comment line that really enables the audience to become part of the program. It's really the 2.0 of podcasting.

Finally, and this might seem like a moot point, but it isn't: Mitch links back to everything he can. He doesn't so much as drop a name or product without finding the most relevant landing page for the accompanying link. This might not seem like a big deal, but as far as helping newbies feel their way around unfamiliar phenomenon, this approach to linking is truly educational -- not to mention good Karma on a link-love level.

Weaknesses
Two things come to mind when I think about what the Twist Image Blog might lack. The first is color. It has a very minimalist design and layout, and in a way that is very soothing and help keep the reader focused instead of distracting them with pomp. But it would be nice if there were some more images (logos, product shots, charts) to accompany so much of the insight that Mitch puts out there.

The second weakness has to do with comments. Comments tend to be held for moderation. I recall reading that they are now live, but I just left a comment, and it is still the case. Apparently, it has something to do with preventing malicious comments, but I never realized that such comments could be such a problem on a marketing blog. I think it's a weakness that Mitch, someone who champions the conversation to such a degree, holds the comments of repeat commentors for moderations.

What I Want More Of
Well, aside from more color/images and open comments, there are two things that I would like to see more of on the Twist Image Blog. The first is, well, something that I haven't seen anything of, so I guess that I'd just like to see it period. It is vlogging. Mitch is just such a natural at podcasting, and such a talented speaker (he does plenty of conferences and the like), that I think 1-2 minute editorials by the man would be extremely intriguing in video.

The other thing I'd like to see more of is commentary and coverage on the world of search engine marketing. Now, I'm not just trying to coax Mitch into applying his talents to analyzing the industry I work in. Mitch actually has some hands on experience in the industry, so I'm surprised and disappointed that I don't see more coverage of it on the Twist Image Blog. He used to work for Mamma.com, so it would be really neat to hear what Mitch thinks about the evolution of vertical and local search, never mind all of Google's various marketing campaigns and product bundles.
