I would like to make a request for training section on CV, as I think those of us who are lucky enough for an employer to pay for training or may have even paid for it themseleves would like to demonstrate they have invested in their careers
Training is not a very good metric of your skills.
One of the things J&J seem to be addressing with CSO is the crap way Internet based job searches work. The main thing they've got going with CSO is the tie in to SO. What you are proposing diminishes from keeping CSO clean, functional and relevant to the quality of a job seeker. I'd even suggest that any employer who thinks training matters is not the kind of employer that CSO is excited about having.
EDIT: I strongly disagree with Stu that this is not a valuable metric of the candidate's skills. There are many kinds of training that are very relevant, such as Agile scrum-master certification, Toastmasters (public speaking), or managerial leadership training. Not to mention all the various certificates that Microsoft hands out!
If I were a 17 year old kid and went to a summer camp for Ruby, I'd definitely want to highlight that. It's going to set me head and shoulders above all the other I-have-no-degree-but-I'm-awesome-anyway sorts of candidates.
EDIT: I humbly withdraw my agreement. I'll leave up this post however so we don't lose the banter attached to it. It still might be still useful to put on the resume, but it doesn't need its own section.
