You can't #hashtag numbers??

I just noticed when I tweeted this that the numbers didn't hashtag!! 

A twitter hashtag is the # sign placed directly in front of a word on a tweet (ex: #nerdsunite) that when you publish it on Twitter it generates a keyword search. You'll notice the majority of posts on TNTML have hashtags in them so when people RT the articles it not only expands to their followers, but to more of twitterverse as well. =) 

#NerdsUnite FTW!!
