Obvious is a financing through advertising. Because ad revenues would only start to come in after the Geomnesia-System has established, there has to be dealt with a warm-up-time, in which the system doesn't yield money (let alone profit). But after that it would be quite interesting for organizers, caterers, hotels, leisuretimelocations (swimming baths, iceskating halls, cinemas etc.) and also for retail shops, to link to their business location via Geomnesia-hash-code on one hand, and on the other hand be diplayed as a symbol on the geomnesia-maps, with further informations connected with that symbols (link to business-website, programmschedule, menu etc.). Probably there has to be a staggered pricing-system (simple entry free, entry with additional infos fee X, entry with link to own website fee Y, being displayed on potentail customer maps fee Z, etc.).
The costs have to be affordable for commercial customers and the pricing transparent. The registration has to be simple, the assembly of features modular and easy. Geomnesia itself could offer the creation and maintaining of data for commercial customers as a sub-branch.
At the beginning the system would be only interesting for private users. If one integrates a routeplanning (Mapsolutions offers that), just as another routplanning-site it would better attract attention. In addition to that the hash-code-system creates a great attraction for users, that want to share "selfexperienced" routes with others
Maybe the "basic membership" for private users has to be free, but then the user can only use basic features (just create single points, no routes; just limited additional infos etc.). In exchange the user has to deliver only few personal data, but will be pursued by quite unspecific advertisings. <gg>
In an "extended membership" (that has to be simple and easy to be paid for; maybe a single payment of amount X via PayPal, T-Online, 0190-Number, etc.) there is the creation of several routes and several additional infos included.
In further membershipgradings there is the full range of features usable, including to integrate selfcreated routes (GPS, routeplanner, etc.) in Geomnesia (using free Geomnesiasoftware, possibly as java-plugin or the like) or getting other routes into the own GPS-device or harddisc. The bigger the membership, the less advertisments the user get's to see, or the more precisely he can adjust the kind of advertisments, Geomnesia is showing him..
Besides there has to be probably a kind of "portalsystem" inside Geomnesia, including chatrooms, forums, blackboards etc. Private users have to be able to easily find up-to-date program-schedules of organizers in an adjustable area around specific mappoints (e.g. his home), travelreports of other users, points of speed traps etc.
For private users the membershipfees have to be affordable without any problems. More than "a few euros per month" is not acceptable, even for the biggest membership.
When the Geomnesia-system is actively used, the user-profiles in association with the often referenced locations (meeting points with friends, clubs, viewpoints, etc.), will build movement- and stayingpatterns, that would be of interest for cityplanners, advertising space suppliers, sociologist, etc. Giving out these data would then be a service of Geomnesia, that has to be paid for.
Or there would be special memberships for these clientels, that would allow special analyzing.
Data privacy for private users and companys has to be guaranteed, connections between living place/leisure places etc. are only given out anonymized.
