Talk:Retro expedition

Changes in categories to current use

I suggest the following changes for more stringent categorising. These are already included in the page draft.

• Remove Category:Expeditions from retro expedition pages. This makes sense because the Expeditions category is evaluated automatically for statistical purposes (most active, active graticule map...) and yields wrong results if retro expeditions are included. They are still included in Category:Retro meetup

• Unify Category:Failed - Incorrect date and Category:Origin reached into new Category:Retro coordinates reached as an equivalent to Category:Coordinates reached.

I think if you allow Category:Expeditions with photos, that implies it's an Expedition, and it should get the Expedition category. If someone is going to retro hashes in an area, I think that area's still active. We're not getting enough ativity to really be picky about these things. --joannac 20:03, 4 March 2009 (UTC)

Of course it's an expedition, but not a regular one, and the date shown in the name is not the date of the expedition. A human or a program flipping through the category pages should rather not include it. That's why I would take them out of Category:Expeditions. A category "Retro Expeditions" is actually not needed because it would contain exactly the same pages as Category:Retro meetup which is the replacement for "Meetup on YYYY-MM-DD". So, reading both Category:Expeditions and Category:Retro meetup would still return all expeditions. --Ekorren 20:23, 4 March 2009 (UTC)

Third retro achievement

I suggest a third (and probably last) retro achievement:

Generic Example Geohash - visit the coordinates (fractions, in any graticule) of the example in the original comic. (Suggestions for a better name are welcome)

XKCD-centurion

Should we allow getting XKCD-centurion along with the other achievements (although, not Last Man Standing, obviously). The origin and wedding achievements will not be available to all participants, obviously (unless the 2 married people travel independently of eacy other). --joannac 20:03, 4 March 2009 (UTC)

Actually in terms of the Centurion (and possibly the XKCD-100 honorable mention and Migration geohash, see discussion there) it doesn't matter where the coordinates came from. Alternate coordinates are allowed there if you actually meet someone at the official time. Whether these alternate coordinates are actual retro coordinates or voted arbitrary coordinates is meaningless, so of course these can be combined. Could be clarified a bit, surely, I didn't think enough about that case :) --Ekorren 20:23, 4 March 2009 (UTC)

Appropriate date range for retro hashes

I'm wondering what constitutes a valid date range when contemplating a retro expedition. For example, this site lists Geohash coordinates dating back to 1928. However, Geohashing didn't really start until May 21 2008.

Would you consider a reaching a retro hash from 1930 to be:

1. Perfectly acceptable
2. Bad form, except for notable dates in history including the Origin Geohash (please provide examples)
3. Not acceptable before date X (please supply date (could be relative to the Geohasher, Origin Geohash exempted)

The reason I ask is that I can see at a glance all the retro hash coordinates using my KML Generator, and would make it easy to hit up a ton of retro-hashes.

Thanks for your input!
