This has been discussed before, but I don't know how widespread it actually is:

blockchain.info allows "alias" names for their wallets.  Look for how to do it at "Account Settings" at the wallet home page, look for "alias".  Pick a word that no one else already has.  "gold", for example already has been taken (I checked), but "durdleman" probably has not, so you could use that.

Then each time you go to your wallet, type in "durdleman" in the "Identifier" field.

Easy-peasy! 

This, and the IRS would never know it's you. 

I had to do this once for a localbitcoins transaction. Buyer did not have a QR code for me to scan. I typed it in from reading it, then he read it off, then I read it off.

When it happened again with someone else I realized he could just copy and paste the address to me in a message.

Thanks. I'll have to keep that in mind if that ever comes up again.

I just saw a thread over in the alt coin section about something similar. Seems someone proposed sending bitcoin via an alias. Edit seems it was necrobumped but it may be of interest to you.

Since we anyway copy and paste addresses, it really doesn't matter.
Moreover, you can save frequently used addresses with a tag in your bitcoin client.

Is this the messaging app everyone has been talking about? You can send actual bitcoins with this? I thought it just used its own gems currency?

I wonder why you cant edit the names of the addresses you create in bitcoin qt, or why there isnt a section to put them in order nicely like "friends" business" "exchanges" whatever.

No bitcoin transactions is possible it has its own wallet, gemz tokens are used for rewarding users for participating within the network through airdrop (to be released soon along with iOS) and payments for different advertisement purposes. Android has been released, i suggest reading the community Q&A.
