Integrate joomla with facebook

Do you want to integrate joomla with facebook for things like :

Allowing users to login from facebook to your joomla site.
Allowing users to comment on your site with their facebook.
Allowing users to like your company page etc

You have 2 ways :

1 way is that look for joomla extensions site for latest facebook integration joomla extensions
See this – http://extensions.ijoomla.com/joomla/communities/social-networking/jfbconnect/joomla/

But this way has one drawback that you never know that the extension you are using now will be compatible with future versions of joomla but second method will always work and it is recommended for develoepers and ones who know html/css/php

2. Manually write facebook api code . It is not so tough
