If you are a user of Twitter, then you’ve probably seen a hash tag or two. The hash tag is sort of like the Twitter equivalent of tagging a post using keywords. The hash (or pound) symbol is used in conjunction with the intended keywords to make the post easier for others to identify with searches or filters.
The default abbreviation for unified communications is “uc”, so #UC became the natural hash tag for Twitter posts related to unified communications. As it turns out, though, UC is also a popular and natural default for University of California, University of Colorado, etc.
The bottom line is that #UC has too much competition and leads to too much confusion, so unified communications experts and vendors have teamed up to adopt #UCOMS.
If you want to tag a Twitter tweet to identify it as a unified communications topic so others can find the post, use #UCOMS instead of #UC. Also, help to spread the word so that the rest of the UC community can make the transition and help end the confusion as soon as possible.
