Social networking has become a huge part of building a brand. Along with that, niche social networking has become a huge thing, as people group together due to common interests or causes. Example, I own a roleplaying network that is basically "Facebook for Roleplayers". A friend of mine owns one for authors/writers to network with other people in the publishing field. I know many people that keep niche networks on their list of ways to contact them or see more about them. It'd be so awesome if Weebly's social icons system would let us add our own icon and link to add to the default ones.
Even better, so they'd match with the icons currently available, if we could specific a letter or two or generic icon to represent our custom social icon link. That way they'd all match and look professional.
Like, I'd love a little book to represent http://www.literarysocial.com, as since it would be for my author page, having my official bio marked there would be amazing. Having one as an A for an Amazon follow, or GR for Goodreads would be great as well. I'm sure there are a lot of people that could think of ways to use a custom icon generator to add to their social icons list.
