Ajay Kamat has reached the age (27), where it seems like a lot of his friends are getting married.

So, as CEO of Micromobs, which specializes in web-based group collaboration tools, he decided to design an app for people to share photos from the happy event.

When it comes to furniture shopping, lots of retailers come to mind – Pottery Barn, Crate and Barrel, IKEA, Williams-Sonoma, plus a whole host of others.

In fact, the furniture industry is so highly fragmented that the top 12 retailers nationally only control a cumulative 12.6 percent of the market.

In addition, a long complicated supply chain stretching in many cases from manufacturing plants in China and elsewhere in Asia and involving multiple middlemen, helps to inflate the cost of each piece of furniture substantially by the time it reaches you, the consumer.

If you’re going to the San Francisco Street Food Festival Saturday, one of the event’s sponsors this year is a startup we covered back in January, Cater2.me.

It’s a natural fit, because this is the startup that has been connecting many of those individual street vendors – people with a food stand or cart in the Mission, a truck, a pop-up café, or a stand at the Farmers Market – with the businesses downtown ordering meals for their employees.

When we first looked at Nextdoor five weeks after it launched late last year, the San Francisco-based startup had already helped people create 550 private social networks for their neighborhoods across the country, 100 here in the Bay Area.

Since then it’s grown to encompass 4,000 neighborhoods in 48 states and is adding at least 20 more networks every day.
