My friend recently informed me about his newest project - Hashwork. Basically, it's Twitter, but for the work environment. Check it out at Hashwork.com. You can use it as a standalone web application or you can use it in conjunction with Twitter.
I think this idea is incredible and only natural. All big releases like YouTube, MySpace, Match.com, Google etc are rarely superseded by any other start up especially when they have achieved critical mass usage. The only way you can "hope" to really get a "piece of the pie" is by carving up a niche within that all-encompassing market. A few success stories: YouTube was followed by YouPorn, MySpace was followed by Facebook, Match was followed by eHarmony and so on. Not all of these niche based products were met with as much success as the ones aforementioned, but for my friends sake, I hope they can do it. Cus it would make a great bar conversation =) (oh hashwork?, yea my buddy was one of the co-founders.. )
Anyways, hopefully Twitter has their hands tied dealing with scalability issues or whatnot so Hashwork has time to gain some ground before they can expand to these niches or other start-ups do.
