This update solves a few problems, and opens up a few possibilities.
You can now create tags unique to yourself. As an example, you can see the #blog.hubski tag above.
To create a personal tag, simply add an @ symbol to the end of a tag. For example, if your username is oscar, blog@ will convert to #blog.oscar upon submission.
Personal tags can be followed and ignored just like other tags. Community tags cannot be personalized.
As always, feedback is much appreciated!
