I put this together because I thought it would be interesting ot get a good sense of what the people who visit this site use for their toolkit on an everyday basis. Of course, some of these tools you might not use at all, but if you do, be sure to share your opinion. Also, let me know all of the other options and tools you use in the comments.
This could start a lot of discussions, "Wordpress or Drupal" or "Sublime Text or Coda", for instance aren't the only options, but I think it would be interesting to see how the community compares the two, as well as what others crop up as the most popular options in the comments.
