PROS: Covers a variety of personal branding issues, often with a sense of humor. Has a useful "beginner" section in the "About" and a variety of resources.
CONS: Wide variety may limit usefulness. Requires some time if you're not used to personal branding. Blog does play a role in promotion of its members (as to be expected). Blog is definitely focused on its subject – nothing extraneous here.
SUMMARY: A diverse resource for personal branding, worth at least temporarily putting into your newsfeed to see if you'll use it.
