I think it would depend on your country population or how many tweets come out of your location. There is really no way of knowing how many hashtags have been tweeted so I would suppose you need to just experment. Maybe start with 200-300 hashtag tweets per minute.Hey guys
any idea on the rate you need to publish to hashtags to trend to locally?
Hmm...there are some live TV networks that ask people to tweet an answer or something using a hashtag. For example WWE gets hashtags to trend all the time without even tweeting the hashtag from their main account. The retweets probably make it trend faster but its very possible without any retweets. Also you need to remember that a retweet is actually counted as a tweet. Not in the accual tweet count but your followers all see it and so therefore twitter gives it the value of a tweet.My understanding is Twitter refresh trends every 15-20 minutes and are mainly based on retweets of a #tag not posts.
