It really does allow you to be much more interactive on here, and reward posts a little more thoughtfully. Plus I really like being able to leave a few cents when someone writes a thoughtful comment, since some comments can be as interesting as the original post.
Good luck in your quest!
I tend to upvote all the thoughtful comments on my posts. Hitting 500 will allow me to keep upvoting comments while still being able to reward authors for their posts. Really like being able to give votes to new bloggers and spreading around some votes to try and help motivate them to stay. Not easy to everything I want with only 20 votes a day...lol.
