Unlike other social networking sites lke Facebook and Twitter, Google+ doesn’t offer vanity URLs for user profiles, making it more difficult to share your Google+ Profile. Instead, Google uses a long string of numbers to denote users (e.g. 117679391504351387685).
The reason Google+ doesn’t use vanity URLs is because those could lead to spammers figuring out the email addresses of Google+ users (as many Google Accounts are linked to Gmail accounts).
As you can see this creates a problem, you don't want people to type a long string of numbers to find your Google+ profile. To overcome this one can use Gplus.to. This simple app allows you to create a short URL for your google+ page. This way it is easier to share your profile with your friends.Mine, for example, is Gplus.to/ankitgupta, which is much easier to remember than a random strong of numbers
Gplus.to fills a gap that Google+ doesn’t currently address. Should Google give users the ability to create vanity URLs, or is it too much of a privacy concern because of its connection to Gmail? Feel free to let us know in the comments.
