I happened to notice this message when I got my beta invitation to socialthing, a new identity aggregator that right now looks a lot like Plaxo Pulse and other sites, but maybe there's more to it. Check this out:
Just head to the link below and you'll get right in! Before you do, make sure you're using Safari or Firefox. We haven't built in Internet Explorer support just yet, but it's coming! Lastly, before you get in, if you think you've stumbled across a bug, first refresh your page (just in case), and if that doesn't work, refer to the last paragraph.
Have you seen that before, with sites optimizing for Firefox before Internet Explorer? It clearly makes sense for the geek audience Socialthing will attract. I wonder how far that'll spread though.
Update: Social thing is planning a slew of differentiating updates ahead. They are one to keep an eye on.
Update 2: Be sure to read Socialthing Founder & CEO Matt Galligan's response in the comments.
