The Next Web reported about 30 minutes ago that Vine users will be able to get their own personalized address.
From the article:
As a holiday treat, Twitter has announced that it will begin allowing Vine users to register for vanity URLs for their profiles. The race begins on Friday, December 20 at 9am PST when those with verified accounts will be able to sign up. All other Vine users will be able to participate on Monday, December 23.
The news was shared in an email Twitter sent to journalists earlier today.
As you may expect, vanity URLs will be in the format “vine.co/USERNAME”. In order to get your username, log into your account on Vine.co and there will be a page that will offer instructions on how to register your profile URL.
Twitter says that it will be automatically reserve profile URLs that “mirror verified Twitter @usernames”. So even though the username is secure, you need to claim the profile by registering for it.
