Stalker
When I build my social media channels, the first thing I do is show them on my website for people to notice. It's really difficult for me to go to each channel and grab the integration code. I need one extension that allows me to show all my channels easily. Stalker is a great Joomla social extension for that need. The main reason I chose this Joomla 2.5 extension because I can show up to 52 social media channels to my visitors: Twitter, Facebook, YouTube, and Google+, just by entering my user ID for each channel. I can also add more networks or customize my icons to fit my template. Moreover, Stalker can display icons anywhere on the site: in a module position, directly in an article or even in a Community Builder profile.
