Nitter is everything I wished Twitter was. Well except the upcoming support for following folks. Viewing the same profile in each is like viewing 2 completely different platforms with how different the displayed content is.
In regards to celebrity gossip and such I guess it depends who you follow. With Nitter if you only associate with people that simply don't partake in those kind of discussions you won't see such discussions. On Twitter it's hell bent on trying to show you what is popular instead of what you asked to see so the same is not true.
