I have to agree 100% with what you posted! I believe that any press release can instantly lose credibility with an audience if it contains grammar mistakes or typos. In a professional industry it is expected that people be able to communicate clearly and correctly to convey any point or idea. Typos are simply a careless mistake that professionals need to be cognizant of when publishing anything! If one decimal place were off in a calculation at NASA an entire mission could go haywire. If a professional is missing one character in a twitter name or misspelled one word in a press release the outcome could be astronomical.
