I did not find value. I set one up many years ago and found that I didn’t have time to keep it up. Having said that, there are some members who are great with social media. I get too busy and don’t have time and then I feel like it actually hurts more than helps because my posts are so infrequent. So I would say, if you are going to set it up, make sure you have the time to keep it up.
Yes, it can be of value, but like with all social media you need to post to it and respond regularly. This does involve a time commitement that you must make or it will not be productive. You can hire a student intern to be responsible for writing and readin, blogging etc.
