Yes, Twitter is unstoppable. And it’s currently amassing an army of Twitter related apps that’ll ensure its reign for a good amount of time. The latest recruit is TwitPic, an application that allows you to post photos and images to your Twitter stream. Now daily ramblings can have an added visual element instead of just the usual plain stream of text. Say you’ve just had the worst blind date ever, but you managed snap a pic of the twit. Now you can go home and post your grievances along with a visual aid to demonstrate your dating woes. TwitPic works from your PC. All you have to do is log in to your Twitter and upload the image or photo you want, then post it. TwitPic is absolutely free.
