Just read a great article on Copyblogger about the 8 habits of highly effective bloggers.
Which habits struck me the most?
2. Effective bloggers are concise.
Short, effective paragraphs are invaluable. Especially if you manage to say a lot in few words
4. Effective bloggers are lifelong learners.
Marketing is constantly evolving. If you forget to pay attention for just a minute, you may get left behind. It is important to always stay on top of and ahead of the game.
5. Effective bloggers are focused and consistent.
Just as you can't please everyone, you can't be everything to everyone all the time. Pick a topic and an audience and stick with it.
