Re: They can keep it
For a technology magazine the first 2 comments sound pretty Ludite.
I have to agree.
Personally, I have not used Pingit, yet. However, I regularly use bank transfers to/from my friends and family instead of exchanging paper money. For me, I already have them set up, so it is simpler to use that than Pingit. However, I would certainly try Pingit/Paym for a new payee, or for someone I would only be paying once.
The twitter handle thing doesn't interest me, but I see nothing wrong with them implementing an additional way to address the transfer. I can see sending to a Facebook account or email address coming next.
