LinkedIn Follow #PowerApps
An underrated feature of LinkedIn relates to hashtags of certain technologies. Experts in the field like to post their articles to LinkedIn before any other platform. You would come across a lot of good resources here. I have found certain articles that I have not found anywhere else that have sold me on how useful PowerApps can be. I follow this hashtag and I think it is valuable to check periodically.
