In addition to all these very useful answers above I would like to recommend the following approach:
1) Write an article
2) Do not hesitate to make any kinds of mistakes
3) Give it to a proofreader/editor
4) Compare your version versus edited one
5) Learn
6) Repeat form #1
P.S. for proofreading i would recommend oDesk, 300Editors or Wordy.
