Thanks in advance for spending your time on reviewing the site. :)
However, I have a suggestion which might make it appeal to a broader audience. When a user creates a login, you can provide a list of celebrities of each category. The user can pick the ones he/she wants to read the tweets from for each category. Maybe adding an option of receiving daily email/rss feed be useful. Also, being able to add all the checked celebrities into the twitter account be also useful.
The target audience is broad.Someone interested in tweets by celebs but does not want to either
* create a twitter account and add celebs one by one
* or feel like reading the celeb tweets only sometimes and does not want to pollute the twitter stream with non-stop celeb tweets.
