I like what you are trying to do, with a stylized "link" icons. I'm having issues with #78 with the reuse of color in the written word, and also would prefer any logo with a left icon to have the words entirely horizontal. #79 was a nice vertical balance. I'd love to see more icon logos that show "linking" which you are doing, but none are quite right. #78 is a bit boring, #70 too heavy, #77 too busy.... but I like how you are thinking!
Can you show #78 with the icon having no blue? More related to the colors used today? Can you find a way to put the words in one line, in colors that work? Thanks!
I really like #171. Thank you for the color changes. Can you make the parts of the icon (sorry not sure the technical term) smooth, ie, take the notch out?
