There doesn't seem to be a "respected" Arduino individual that I know of*
*There are a few blogs with a lot of respect but are managed by multiple people. If there was one, single respected person, he/she would probably be posted here already.
- Hack a Day: They post about many fun and creative projects, from automatic flame throwing pumpkins, to DIY heat cameras. I don't know if this is the thing that they would blog about... it's more of a "hard core EE" site. Some beginners that know a lot in other areas but not in Arduino might come here if anything's posted. Also, we might be able to gain some more advanced users and/or questions. EDIT: We were mentioned on this blog!
- MAKE: They post a lot of beginner oriented projects and tutorials. They also have a store and a magazine. Again, they wouldn't probably won't just put a link in.
- Lifehacker: They post mainly tips for the geeky person. If you don't read it, I would recommend it. This one would be hardest to get a link only: but I have an idea to get it on one of this sites...
How do we get a link on a site that big?
We don't, really. We need to generate great content of how to do something, find a clever solution, and send it in to one of those. For Hack a Day, the toilet paper question might get mentioned if it generates a great answer. Make probably would need a good tutorial on how to do something that they could rewrite with pictures (and throw in a link). Lifehacker?: Anything that would make your life more productive and is fairly easy to DIY, even for a software kind-of-guy.
I doubt that we could get a mention on all of the sites above.
You wanted a list of "prominent" blogs in the community, I gave you what are read often. (Making it a wiki: edit this list if you want to.) But I think if we work hard, we can get something on a popular site.
But wait... there's more!
One thing often overlooked is Wikipedia. Seriously. Sometimes, Wikipedia comes before the actual site in Google. We currently aren't ranked on Google. If someone was Googling something along the lines of, *arduino forum site***, Wikipedia may come up on the first page due to its high SEO. I think we should try all of the above sites, but Wikipedia doesn't need any real approval to be posted about. It has great SEO, and we might even get up into Google sooner than without (with cross-linking sites). Note: I'm no expert at SEO, so correct me if I'm wrong anybody.
**Although I hate this, we should probably put some mention about being a forum in the Wikipedia article. It'll get better ranking in Google. We could probably even do:
Arduino Stack Exchange is similar to a forum, but it is categorized as a Question and answer site. Foo bar blah blah...
