One of my Twitter friends recently posted a great article by Xavier Lur, who is a 15 year old Singapore student and also the editor of TechXav. TechXav, a technology blog written by teens ranging from 11-15, was founded by Lur in 2009 and is great site which shares news and reviews on technology from a youth’s perspective.

The article that actually caught my attention was from July, but I found it too entertaining and impressive to not share. 30+ Funny & Weird Twitter Applications give us a application-by-application rundown of Twitter’s most entertaining (yet mostly useless) add-ons.  If you have a couple of minutes, I highly suggest you read through the entire list, but below you can find my favorite 4 apps taken from Lur’s list:

Track This lets you track your UPS, Fedex, USPS or DHL package via Twitter.  Each time the package changes locations, Track This will notify you of its whereabouts.  No more waiting by the door for the UPS guy to arrive!

Foamee is Twitter’s answer to online flirting.  That special someone will be notified that you have purchased them a drink, but the kicker is, you’ll have to actually meet up with them to redeem it.  The sender or receiver can then confirm they actually purchased/claimed the drink, so all of your Twitter friends can see you are a (wo)man of your word.

Overheard.it is a personal favorite of mine, as it reminds me of one of my favorite pre-Twitter/Foursquare websites, Overhead In New York. Users anonymously tweet about silly things overheard throughout their day.  Great for a giggle or to pass time waiting for the bus.

TwitterMosaic I find really fun (especially as my News Feed was recently flooded by “My Year in Status” posts).  It compiles a collage of all of your Twitter friends and lets you drop the picture onto mugs, t-shirts, bags, etc.  Next Christmas, Twitter Mosaic mouse pads for everyone!

Finally, my least favorite application.  But only because it thought I was a dude.
