What are the differences of Picotea?

Currently there are other free microblogging sites. With Picotea we want to differentiate from other services by offering something different. How do we differenciate?:

• Here you can create groups or join existing ones to peck on things that interest you. Although not follow anyone or no one follows you, you will communicate with all group's members.
• You can also create or attend group's events to peck on a specific event. Although not follow anyone or no one follows you, you will communicate with all event's attendants.
• Do you want to follow the talks?, in Picotea you can do it. You'll see what post is being answered from other posts and other responses that has had a particular post.
• You will have the ability to search other users in a simple way, you can find people for your affinities with them, location, for his studies and his work.
• You will be able to multiply your web presence. From Picotea you can publish in four sites at the same time.
