For a campaign to matter on Twitter, its hashtag has to grow into a trending topic. Without people talking about it and using a specific hashtag on their posts, you might as well kiss your hashtag into oblivion.
If, however, it gets into that little box at right side that lists top trends according to location, then you can rest assured that others will be curious and try to ride on.
The attention will be worth a whole lot more if you've managed to trend not just in the US but worldwide.
Here are some of the most talked about hashtags in the past 24 hours. And since it's Valentine's Day, we can only expect that the trends will be mostly related to love and relationships.
#CandyHeartRejects
#CandyHeartRejects features humorous photos of candy hearts that did not or never will make it to the pack of Valentine candy hearts likely distributed on Valentine's day.

#SkipBeMyValentine
Because Daniel Sahyoune, or Skip, of the boy group The Janoskians is so popular, an invitation to retweet a Valentine wish naturally trended among his millions of fans worldwide.
#CS4
Fans of @DJBandCamp rallied on Twitter in anticipation of DJ Bandcamp's newest mixtape #CS4 (Cuffing Season 4) featuring James Lloyd. CS4 was released at midnight to Valentine's Day.
