2 things wrong with this post.
1. it has a read more link, if it is worthy of discussion then post the article here in its entirety and let us discuss without offsite links.
2. it is a link to a grammar lesson and last I checked no programming language that I know of has a grammatically correct parser so this post has no place in the web programming forum.
3. I know I said 2 but I'm in a venting mood and I can see no purpose for the original poster to post this other than to increase post count and to add another little bit (read miniscule) of google
PR to his affiliate sites in his sig.
All done, finished venting, move along, nothing to see here. Unless of course the op would like to pull me up on my grammar (if he actually read the post he links to of course).
