Making the profile pages better is really needed. It's sad that the GSoC 2013 project is not yet implemented - as a first step.

However, I am against displaying data of WordCamps/ WordCamp Central on those profile pages and I give my reasons for that:

There are a lot more events within the WordPress community that are not organized by the WordCamp Central/ The Foundation/ Automattic - such as other conferences, meetups or other barcamp-like camps, like the WP Camp in Germany for example.

What should be even displayed from WordCamps? if you have visited one? If you have spoken at one? Who has all that data? -- And if that data still exists from all these years, should it be public at all?

And also: you in the U.S. have lots of WordCamps, every week almost is one --- so it would lead to that, that for some "rock stars" in the North American WordCamp scene the profile page will burst with WordCamp stuff: visiting, speaking etc. ;-)

For other parts of the world: there is a growing number of WordCamps/ WP Camps, Foundation-organized or non-Foundation-organized, still, taken for one country or region you rarely have those numbers than in U.S. ...

Lots of European countries have "only" one WordCamp per year, if at all. Some countries have camps/meetups/conferences but not with the Foundation in that (for whatever reason).

How would you manage all that to not make much differences between the whole global community?

Example: You were to 10 non-Foundation organized events but none of them would then show on the profile page? Would be no good I guess...

All in all we should not include such event data, at least not in an "automated" kind of thing!

The better way would be to make another textarea maybe where users can fill out event data manually - but fully optional?
