I recently joined Twitter because I knew a number of people that were already on it . So, I signed up for Twitter and sent out some Tweets to the people that I knew. And you know what I got…everyone got back to me and said ‘Get rid of that egg!’. The ‘egg’ they were referring to is the default Twitter profile picture that shows if you haven’t uploaded your own photo. So, to avoid grief, I would recommend that you have a photo ready and to upload this photo as your profile before you send out any tweets. Just so you know, the Twitter profile picture specifications are that the photo must be a jpeg, gif or png file and the file size must be less than 700k .
