Hi Adam,
You say " ...Its true I see countless Panoramio account that are not active, seems like most members created accounts years ago put a handful of photos and never used it again. Comments / questions left unanswered, those countless accounts are just like old houses with cob webs instead of people"
It is not uncommon that in every popular website there are a sizable percentage of inactive users for several reasons -
1) Expired people
2) People ( at the start of the Panoramio Web Site) who forgot their log in password & lose track permanently & open a new account if their previous account do not have much of photographs
3) Dormant (really inactive) due to loss of interest
4) Active in some other field of work & so currently not active in panoramio - later reactivate their account
5) Many users limit their activity with a limited resource restricting to their own residential village or locality
- this really happens where people have opened accounts with a borrowed net connection or from their workplace & unable to follow up for want of equipments
6) User Opening more than one Account will be active only in one account.
As I already suggested the photos, with incorrect mapping reported, if unanswered or not corrected for > 30 days may be removed from Google Earth / Google Maps.
The inactive accounts may be terminated after a specific period of time say One year or so.
This is the way we need to clean-up Panoramio Site incorporating such features that were claimed to have been added in "Views" and not by killing Panoramio
Please think of the active Users which are in no way in small numbers - possibly the number getting improved with the advent of new technology & smart phone.
Viewers base will depend on the display of photographs Mostly in Google Earth. Smart phone users though equipped with Geo Mapping facility they do not add proper title or description of the place / object photographed unless they do it again in the Desktop at home. Photos with no title is like a letter with no address on envelop. Search engines will also not take the viewers to such photos of Specific place.
Now, it is high time Google review their decision, in a juncture the campaign to Keep Panoramio Alive is nearing 10,000 petitioners -and so many cannot be wrong in persuading Google to keep Panoramio Alive.
Panoramio may be allowed to coexist even with a different name "Panoviews" ( if Google are planning to commercialise the website !) vis-à-vis Google Views
