To hashtag or not to hashtag…
This past year, the hash-tag became more popular and migrated from just Twitter to many other social sites.
Now though, Facebook has decided they no longer want to be a part of the hash-tag coop. They will give any posts that have a # a lower quality mark, which means it will be seen by less people.
So your January Market Tip, use it on Twitter and Instagram, but do NOT use it on Facebook.
