Is laziomania.net the official site for Lazialis (that does not know italian) ?
My personal opinion is that it sucks, and compared to asroma-addict, the design is really aweful (it really hurts to admit it).
Laziomania is not officially associated with SS Lazio. Like Aca said it was created by former Xtratime member Mattias... as a fan, for the fans.
The other site you mentioned was also started by a former Xtratime member (Il Lupo), in certain ways that site is better but don't forget that they have a whole team behind it and Mattias is just a student running Laziomania in his spare time.
You have the english page there aswell, but IMHO, that really sux, since not all the articles are translated and you can't get the news fast as somwhere else.
And I must say this. How can you say Laziomania sux, when that's the place where most of the Laziali get their information ? There are a lot of people taking care of that site, and the job is not that easy you know. AS ROMA ADDICT has some nice designs, but it's too childish and colourless. The only thing they do good are the picture design, otherless, it's just OKAY, but not as good as you said.
Laziomania deserves the respect, as it was created by a student, who through the years became very well known to Lazialia's all over the world for his site.
