I do not have a favourite blog, but a not of vlogs have helped me make purchase decisions by showing the usage of products! Especially on YouTube and TikTok.
There are alot I like, but the one that gives you continuing advice and update information, as if they are reading your mind is the best. Pat Flynn, Neil Patel, Tim Denning, Greenpeace, Tim Morrow(CopyBloggerguy) all are awesome.
My favorite blog is Cracked.com. It's pure pleasure reading. Or is it? Cracked dives into topics we all think we know inside and out, and reveals that due to not being taught properly (or at all) in school, or not being reported in the news, or reported with bias, or ignored by the media altogether, and not really discussed at social events, there is a HUGE wealth of knowledge about history, current events, the animal kingdom, human nature/psychology, and other topics that don't really get talked about. The blog has to be taken with a grain of salt because it's a humor blog, and some of the content is made up. But it has changed my mind about a few things. One example is even though I thought I knew the real story of the "discovery" of America (what we now call the United States, that is), I didn't. I was especially appalled that not only did the settlers intentionally wipe out the Native American population and break all kinds of treaties for land, but they brought European diseases that also decimated their population. You don't learn that kind of thing in your U.S. History class in high school. History always bored me, because it was full of minutiae, facts, and figures about United States politics, always focusing on how we become "so great" as a nation. The truth is harder to swallow, and you'll find it, and a lot of other interesting tidbits that can give you wisdom, on Cracked.com
I like these blogs because they're packed with value to help young people live better lives. They're also written in a compelling way, and this keeps me reading from heading to heading.
Their articles have a strong sense of going somewhere. I love it.
At the moment, I am teaching blogging and for me, I follow QZ.com and Cracked.com as they are both fun, and sometimes touch upon business and pop culture.
