Zach has a huge following on the internet, his reddit AMAs have over 10,000 comments (makes them some of the most popular) and he has almost 200,000 comment karma just from them. Photos and clips from Scrubs are a daily occurrence on reddit and he has an engaged Twitter following. Melissa Hart by comparison is relatively unknown, her Twitter followers don't seem to be engaged at all with 10 - 40 retweets per tweet and Zach has anywhere from 200 to 2000 for his tweets. He's in a different league to her and that doesn't even consider that ZB has a previous successful project, a cast of people that also have a big following and the project looks cool.
