LinkedIn now gives you the option to display a 'Follow' button as the main button call to action on your profile page, as opposed to the current 'Connect' default.
This has been the main option for high profile users who are in LinkedIn's 'inFluencer' program for some time, but now, all users will be able to do the same.
"When members follow you, they are more likely to see your content in their feed. This allows members to stay up to date with topics they care about and join your conversation. We've heard from you that it can be overwhelming to receive a large volume of connection requests from people you do not know. This option makes it easy to establish a relationship and share your insights with people who are interested in what you have to say."
