Gatorpeeps: do we really need it?

I'm all for new South African 2.0 sites. Have just heard about the launch of Gatorpeeps which is a twitteresque microblogging site with a focus on communities in Africa (or at least this is what I can gather). I haven't signed up and so can't comment on actual functionality but that's part of the problem. Do I really need another microblogging account?

Somebody called kilps asked the question "is this really needed over twitter? why not just sit on top of twitter as an african filter of sorts?". I have to agree. Voracious social media consumers and contributors may disagree but we're in danger of diluting the value of social media, ironically, by launching sites which are similar in function to existing properties which have critical mass.

Of course, this is not meant to be anti-innovation, simply anti-emulation if the value of the new site to a clearly defined niche is not defined and/or if the new functionality it brings is similar.
