I don't want to spoil your fun (and this
is admittedly lots of fun :-) ), but I suspect this page is a bad idea. It encourages the idea that we ought to distinguish ourselves based on our seniority, as opposed to our ability to write good articles, which is what
really matters. I think we ought to do our best to underemphasize seniority, which can be used, often illegitimately, as a way of deciding who to accord how much respect. Of course, sometimes how long someone has been here
does bear on, for example, how well they understand Wikipedia policy and why Wikipedia works as it does. But it
doesn't bear on much else.
For "historical" purposes :-) , perhaps we should each keep a record on our own personal pages of when we arrived. That should do the trick, eh? Having the data all on one page invites comparison, thus the above-mentioned problem. --LMS
