It depend on how you use it.

If you wanna learn a language, I recommend you try to use it then you will find italki is a good language learning website.

But if you use it to make some friends  as Facebook or other social network website, I'd reather you go to there.

I think it's amazing website,

try to learn and practice any language you want,

& help others to learn your language,

get fun,

make friends from all the world,

but always try to respect others, to make them respect you , Best of luck :)
