It is an “interesting” service because:

(1) You do not know how it is done.

(2) It actually guarantees a fixed number of RSS subscribers within 24 hours.

RSSExplosion services range from $20 ,with a 20 guaranteed subscribers, to $90, which guarantees at least an increase in the number to at least 100.

Has anyone out there tried this service?
