Agreed. 100% go ahead and give yourself a vote the same you would anything you come across, if you find value in it, if you are proud etc. People know when they are being ding dings- voting every comment they make etc. Also, many don't realize that they have wasted their voting power and it means nothing and just looks tacky. Use those votes to thank and cheer on authors/artists you want to see more of and you will have a world with interesting ideas available to you!
