I tend not to leave a leave a response, but after reading through a great deal of
comments here 25 Amazing Open Source iPhone Apps | iPhone
Tutorial | iPhone iOS4 iPad SDK Development & Programming Blog.
I do have a few questions for you if it’s allright. Is it simply me or do a few of the responses look as if they are left by brain dead folks? 😛 And, if you are writing at other sites, I’d like to keep up with you.
Would you make a list of the complete urls of all your public
pages like your twitter feed, Facebook page or linkedin profile?

Have you ever considered about including a little bit more than just your articles?
I mean, what you say is fundamental and all. But imagine
if you added some great visuals or videos to give your posts more, “pop”!
Your content is excellent but with images and videos, this website could
undeniably be one of the very best in its niche. Fantastic blog!
