2017.01.26 New Chi.Bike URL! New SSL use. Hosting moved. Email down. Version 5.00 announced.
Chi.Bike has been added as a shorter, easier to remember URL. Pass it along. Going forward I plan to use "Chi.Bike" primarily and let "" become a deprecated legacy name. All the same URL's work, just shorter and funner. For example Chi.Bike/divvy finds the Divvy stops nearest you.
Secure connections became required last fall by most browsers and APIs when GPS info is in use, and for a time Chi.Bike navigation features could no longer determine a user's location. I've recently finished updates to meet this new requirement, and moved hosting to my personal domain for SSL. As a nice side effect, it seems to be much faster now!
This project is now nearing EIGHT years old. It's been so stable and needed only such minor changes that the version number has been slowly stepping through 4.9x for several years. Given this round of updates I've decided to finally up the version to 5.00, even though no new features were added.
Finally, email is currently offline due to the hosting changes, so features like "Text WHERE to to catchup." will get no reply. But I expect to have ALL features back up before spring.

... More than three years of stability. v4.99

2013.08.29 Major navigation enhancements in recorder. Now automatically re-centers and re-zooms after timeout, if manually zoomed or dragged. Automatically zooms in after a period of showing an overview, when started showing directions. Tap self icon to zoom way in to current single block, tap again to back out. Periodically automatically pull back zoom to show surroundings, just a few seconds every half minute or so. This also forces refresh of icons which Google sometimes loses. v4.97

In print, a mass should still use it's individual address, but when active users can simply use u. This applies to all features such as posting, commands, and follows. (v3.0)

2010.12.29 AUTO (continuous automatic) postings now distinguished as lower status from GPS postings (user tap), and not included in default follows.

2010.12.14 Added speedometer display. When using GPS auto-post, once moving, each posting calculates and displays speed using distance/time since prior posting, limiting to reasonable min/max ranges. Speed is logged and appears on such postings in chatter.

2010.12.13 Improved map zoom calibration to use actual calculated miles per pixel. Interesting exponential math dealing with Google Maps tiles. Also revised equation for distance calculations.

2010.12.13 Added live police radio scanner audio feed link (labeled "Alerts") to bottom of Air (end of weather page). Dynamic MP3 stream URL, periodically re-fetched and parsed from offsite ( parent page. Works on iPhones.

2010.11.24 Improvement to DEFAULT Mass. New "NOW" (now@Chi.Bike http://Chi.Bike/now) catch-all mass created, open for any local bicycle related chatter. Also monitors "massup" Twitter and Upoc feeds. System now defaults to featured ("Now") mass if next is more than a few days away and prior is more than a day past. Formerly always simply defaulted to next (/current) mass. Posting by Hotline option now only shown (and applicable to) default mass. Also improvements to chat hour range checking to better handle admin off-day broadcasts. Also added decoding of HTML symbols for readability in text messages.

2010.11.23 Geolocation lookup now attempted on any postings where text contains something address-like. Determines GPS automatically (if absent) if identifiable location described (such as address or intersection). All posting types may now potentially contribute to Plot data, even Cues and bare SMS.

2010.11.16 Perfected GPS auto-posting. Location now auto-follows, uses highest accuracy, defeats caching, and uses active map with bicycle layer (formerly used static image fetch). Also added FAST mode (posts every 40 seconds versus 5 minutes). Also now retains prior description until new place name lookup completed, to reduce raw LatLon postings. Also internally converted to AJAX (a "Web2.x" method). Postings now sent in background so app never leaves page. Eliminates disruption due to spotty network (posting may fail but page doesn't halt). AutoPost can now be added to home screen and operates on iPhone as pure standalone WebApp.

2010.11.08 V2.x series tested well lately on Chicago Critical Mass, Midnight Marauders, and Chicago Ghost Bike Tour rides.
