I stumbled upon something very cool specifically for those of us who are constantly looking down moving our little thumb around on our Blackberry Pearl.

Social networks are popping up everywhere these days with the big dogs still out there.  MySpace, Facebook, Digg, Twitter and the rest.  But, there’s a new trend toward niche social networks.  These are social networks where everyone starts with one thing in common.  It could be a genre of music, a hobby, or in the case of Blackberry Ave, an addiction…

Blackberry Ave is like most other social networking sites.  It’s all about being social and networking (duh).  But, this is different.  This site is designed to be viewed on your Blackberry browser.  Of course it works great on your Mac or PC, but it’s designed to be a WAP site. There is a rumor, if you try to view it from an iPhone or iPod Touch, you’ll get a special message.  I don’t have one so I’ll have to check at the Mac store to see what it says.

The other thing you’ll notice about Blackberry Ave is the listing of PINs.  Before I had a Blackberry, I saw people post PINs on a website and wondered if they were opening up their bank accounts to theft.

If you’re one of the underprivileged without a Blackberry, a PIN is what you use to message exclusively between Blackberry users.  It’s like your AIM or MSN screen name but it only works with the Blackberry Messanger.  Which, by the way, only works on a Blackberry… neener.

There’s also a very cool feature giving every user 10mb of free space on the site to upload your favorite ringtones, wallpaper, themes, or whatever.  Not sure if the owner is going to be able to keep that up.

As of this writing, Blackberry Ave is just getting off the ground after launching 2 months ago.  But, already there is a great group of VERY friendly people on the site. One in particular, is a Blackberry addict who goes by Bull.  He’s got to be one of the most active people on the site as well as one of the most helpful.  Not only does he have his own blog at BloggedBull.com, he’s also writing reviews at BerryReview.com.  Make sure you find him and add him to your friends list.

The “Tom” of Blackberry Ave is a guy named Luigi Raw.  He’s hanging out in Leeds in the UK and unlike Tom on MySpace, he doesn’t force you to be his friend.  So, make sure you take some time to add him to your list of other addicts.
