As our industry has grown the knowledge has greatly expanded and so has the number of experts. People that have probably forgotten more than most will ever know, like James Speed and Debbie Love, have passed on what they know to so many and that next generation has expanded on the knowledge base and passed it on again. It’s been a great way to share knowledge with those that want it and make the industry better.
The concern is knowing who the new experts are or aren’t, and therefore knowing who to take advice from. Many people that portray themselves as experts aren’t and it seems like they are more likely to present themselves as experts than the people that truly are. Combine that with the ease of self-promotion via social media and suddenly every “expert” has a platform to spread their lack of knowledge. The takeaway from this should be to take advice with a grain of salt until you are sure the person giving the advice is credible.
