You can't write about Revit blogs without mentioning Revit Oped by Steve Stafford. Steve's blog is infamous within the Revit community and he is a regular presenter at RTC with 'What's new' in latest releases.
It's updated regularly and the information is always educational and of great quality. If you have read some of my blogs you will have seen a few links in the past to some of his articles.
For something old, see Revit Zone by Ian Nichols. Ian writes some really good easy to read step by step blogs about Revit. I always send beginners to this website for the fundamentals section which has blogs on things like view range, levels and design options.
This brings me to something new. Last year Ian began a new site over at BIMscape where most of his new articles will appear. So if you like Revit Zone, BIMscape will also be worth keeping in touch with.
For something different I have recently started reading The Midnight Lunch by Ceilidh Higgins. It's not always about Revit and captures design in general, however Ceilidh is an interior designer and writes from a different perspective, hence why it peaked my interest.
Practical BIM by Anthony McPhee is another blog I enjoy reading. Anthony's blogs are often about discussion in practically applying BIM in the real world of design offices. His articles have sometimes caused some debate over at LinkedIn, but I think that's the point. Afterall, discussion and debate on relevant topics can breed new ideas and our approach to BIM and its use in the industry.
Other rated blogs I keep in touch with worth mentioning: In no particular order....
