I did a quick stage of research on current logos for both social media sites and networking sites, seeing how colour, shape and imagery were used, and what attributes of the platforms were marketed.
For Pionear I felt that it would be best to produce a logo around a P, but wanted it to be easily distinguishable from the Pinterest logo. This would be done by making the logo more formal and using a different colour. It would have to work in black and white also.
I produced a series of sketches, based around the idea of a stylized P, thinking about networking, linking things together etc.
Ideas based around connections and links
Hephaestus (god of craftsmen) has a symbol of an anvil. It was too conceptual in nature to work though.
Ideas based around expanding networks
From these sketches we decided upon the Paperclip style P, but felt that it was too business like and needed to be less formal. Experimentation led to the P being turned 45 degrees to look like a mountain which tied in nicely with 'pioneer'.
I decided that an absence of colour was better and more professional, using a slightly warm black (0,0,0,97). I also swapped the font to something more bold and suitable, Futura Bold.
