Improveo or Improvio?

IMPROVIO

• Looks younger, sleeker and more easy-going.
• Takes less space on the website.
• It shows that the people behind have self-irony about improvization.
• Many people like understatements (perhaps one of reasons for slack's success: employees enjoy a funny name ... not sure if it's the same type of irony with "improv" .. perhaps we should be more serious)
• Looks better for most non-English natives
• Logo tells “improve world” only implicitly
• Easier to type: i+o next to one another on keyboard
• Plainly abbreviated as IO.
