chrismessina, 
On the topic of hashtag accessibility, I stronger concur with @markwyner's points:
Should hashtags be grouped at the end of a post or is it okay to add hashtags to words inline? Screen readers will treat them the same either way.
Is it necessary to capitalize single words? No.
What about branded words? This is more complex, but as a rule of thumb it’s okay to capitalize branded words as they are.
