On the page http://careers.stackoverflow.com/cv/edit, when one is adding experience, with the
IsCurrent checkbox ticked and the
<input id="tags"> with focus, the
class="field-help" for="Tags" tooltip contains the text:
A list of up to 10 core technologies you used on this job.
I know it is a minor change, and very picky, but think it is worth mentioning that given the technologies listed are for the current position, the tooltip should probably say something like:
A list of up to 10 core technologies you have used to date on this job.
