Quierochat is a Spanish Chatroulette alternative that first started in 2008 and since changed to a Chatroulette type site somewhere in 2011. Since then they have grown to be popular both for Spanish speaking users and international users with about 800 people online at any given moment.
The site is available in many different languages but mostly Spanish speaking users use Quierochat. The speed of the roulette application is good but there are not as many users online as some of the other sites like Chatroulette. It has basically the same features as chat roulette and does not offer any other innovative options like some of the other sites listed on Chatroulettesites.com. But some sites that don't offer anything different are still very popular, just look at Chatpig as an example.
Quierochat.com ranks in the top 100k in Alexa. Although it doesn't meet the top 10 Chatroulette sites, it's not too far off from this list. It has been steadily growing and will probably make it into the top 10 soon!
The site's interface is not easy to use and you have to click around before you are able to actually find the roulette application. Also there is a lot of advertising in the roulette as well as the site works slowly at times. All in all it is still worth checking out especially if you are looking to connect with Spanish speaking strangers.
