How to sign up to Twitter and create your profile
Your profile page is effectively your “shop window” so try to make it unique, something that says who you are and what you do. Your username can be your own name (e.g., @JohnSmith) or something a bit more esoteric (e.g., @mathsgenius). Remember though, if you use your own name, it may be easier for others to find you.
Use your profile to tell people about your research and experience, what you teach, and what your interests are. Link to your blog or website too, so people can explore more, and try to add a photo so people can recognize your tweets immediately on their feed.
Who should I follow on Twitter?
Following the right people and organizations automatically personalizes your Twitter feed (the list of tweets that come up on your home page) and helps Twitter tailor the recommendations it makes to you.
You are bound to have a list of colleagues who already use Twitter, so you can start with these. Then think more widely. Follow people you admire, organizations you have an interest in, media outlets, and researchers working on related areas to you.
You can also use the Twitter list functionality to group accounts you’re interested in and create a mini feed so it’s easier to keep up to date with their latest tweets.
