I like the product, but the Howdoo visual identity is brilliant - logo, colour. They have thought things through...I have joined 30 groups or so on Telegram. The Howdoo one is the easiest to find 
to some people, and this is true for some ICOs, it wont really matter too much about the logo/colour imo, as they are doing things behind the scenes, but this IS social media.. this IS what people need to recognise instantly, and this is a winner right out the bat, as you said, I got like 50 tg groups, I can zoom to Howdoo in an instant, the hand, the colour, everything, perfect start. Aside from all the cool technical stuff they are doing, its clear they want to be a standout brand.
