I agree somewhat with Acroplex. When I bought tel the about.me is the kind of potential I saw in the tel and I still see the potential.
And I do get frustrated by some of the limitations, but its a love/hate affair because I would not have made some of the sites I have without those tel.
But I think I like them even more today :D
I did some research about what I got visitors from, and copied the formula, applied it to all my .tel folders in the directory.
That was two days ago. Today the traffic was doubled to trippled.
Still it might be because of christmas closing in.
But it would have been impossible to make with an about.me page.
However since about.me is not your own domain name. Which is a big difference. It does also not have the potential to be used as phone numbers which is another big difference.
Its still a subdomain and in that sense its still like another facebook and as such its not as optimal or pro to put on a businesscard for web presence as a own domain name.
Since its not your own domain name there are other drawbacks, it will not rank as good in searches, cant be used in many of the ways you can use a tel such as for a directory, internal company directory etc etc.
