Twitter has added a features that allows you to create a list of your favorite people you’re following and would let others follow them with a single click. Currently, as this Mashable blog post states, this feature is available to a select few, but gradually it’ll be available to all Twitter users.
This I think is a nice way of recommending people and this will help you gain more followers. Also, as it happens in almost every sphere in life, this features is firstmost being offered to well-known Twitter users, but the good thing is, if they recommend you in their list, it’s much more beneficial.
