[OSM-talk] Lots of personal markers

[Justus-bulk at Piater.name]

Hi -

I'd like to generate a personalized, interactive world map containing
a marker for each of the (hundreds of) addresses in my address book.

Google Maps apparently has an API for such things, but I'd prefer a
"free" solution. Can OpenStreetMap help me here? Or any other free
(on- or offline) service/software?

Thanks,
Justus
