In my attempt to keep up with the ISTE conference tweets I am using tweetdeck.com. A nice feature about Tweetdeck is the ability to keep track of multiple hashtags and tweeters. This year ISTE is breaking from the hashtag pattern of last year and adding an additional 2 characters. The official hashtag is #ISTE2014, however many tweeters are using the more succinct #ISTE14. Not wanting to miss what my PLN is sharing on the shorter hashtag I figured out you can modify the column in Tweetdeck to accommodate two hashtags.
And now I have 2 hashtags in one column.
