Every time somebody creates a post,
leaves a comment with a unique hashtag or
adds a hashtag to his or her group/event
description a channel is automatically
created for that hashtag.
You can create and follow any channels
you like based on your tastes or interests.
Hashtags are a great way to
attract new guests to your addresses as long
as the hashtags are neither too broad
nor too specific . #Learning is a bad hashtag
because it's too broad. #SmallRiverXYZinRegionABC
is also bad, hardly anyone has heard of it and no other
user will ever use it in their content.
#EnlgishPrepositions or #AltaiRegion are perfect:
not too specific, not too broad.
