I want to send out cards with my Google+ profile. I already have a Facebook vanity url, but wondered if where I can change my Google+ profile to something resembling plus.google.com/bloggermaven instead of the nonsensical number that my profile currently has in the url?

Google+ does not provide a vanity URL, but you can create a short URL for your postcards via a service like: gplus.to/

where you can create a vanity url that looks like gplus.to/bloggermaven that will automatically redirect the user to your G+ profile.

Other similar services are:

• plus.ly
• topl.us
• gplusid.com
• dirpl.us
• gplusnick.com

Another possibility is to use your .htaccess file to create a redirect from a custom url on your blog to your google+ profile.

E.g. yourdomain.com/+ could redirect to your Google + profile:

It is very regrettable that Google doesn't issue vanity URL's, but as you can see, there are work arounds available.
