Interesting. I was invited by a colleague to join her on the Naymz network and as she's always ahead of the game, I decided to give it a go. Having now completed my profile (or having done my best to do so), I have to say I'm underwhelmed by the experience. As you can import some info from Linked In, I guess it's newer than that but as such, it could learn a few lessons from the established network.
Although I'll use any professional forum to keep up to date with the business world and keep the Sarah Hall Consulting name out there, it helps if they are easy to use and edit. This one does not have obvious set up steps to follow, seems impossible to change where info has been inaccurately imported and quite frankly is a poor 'me too'.
Nevertheless, that said I'll give it a go and try and remember where I'm linked in to what - and will attempt to stem my irritation at the z in the name. I'm evidently so not down with the kidz!
