So I present to you, dear readers, The Johnson ExoLab @Harvard! Since Apple discontinued iWeb, I decided to try out an online WYSIWYG editor called Wix. I have to admit, I didn't search and test drive many options. But after signing up for a premium account, I really like the Wix editor interface, and $12.99/…
