Just lately, I have been getting into the Twitter hype. It's a great source of information, and comes in very handy. I hope somebody would be able to answer a couple of quick questions for me. I was first given an option about OAuth when I downloaded Twicca. I didn't know whether to approve and use this option or not? Is it safe? Second question, will I encounter any problems if I have more than one Twitter app running on my phone?
