An evil online blogging system that tricks you into joining it by sending you an email asking you to retype your hotmail details.

It then annoyinly sends the same email, in turn, to each and every person on your contact list. ARRRRRRHHH!

It is a friendster system where you can add your friends from your email list and add new friends from all over the world. All latin people are on it. It seems to be the latin myspace; and soon, it will become the asian myspace. A lot of people from India and Pakistan have joined, and if you include your email address, they'll talk to you.

hi5 is simpler than myspace, but lately, it has changed so you are able to modify everything on your page. You can see who has visited your profile and you can send "testimonials", not "comments", which makes testimonials sound serious. If you send someone a comment on myspace, you dont even have to know them well, it can just be a "hi!" but if you send a testimonial to someone on hi5, it has to be something amazing that describes how great that person is and so on.
