In an effort to create myself a PLN (Personal Learning Network), I created myself a LinkedIn account. I have found it fantastic in creating a network of musicians from AROUND THE WORLD that are keen on education. I have had many people from the US and Aus asking to LinkIn with me and have also had a few people asking for opinions on their educational work.
A representative of The Pascale Method for beginner violins messaged me through this site asking for my opinion and feedback on the method. I also had the owner from Things4Strings message me in regard to their products.
It is great to find new people who are keen in the same area as you. The endorsement of skills is another way of linking with people who have the same interests and skills as you.
