Vertical search used to be a hot topic in 2006-07, with search being applied to horizontal industries like travel, B2B (see this article for a big list of such search engines), products, health, people etc. Read this 2006 readwriteweb article for a good refresher. In 2009, many of these vertical search sites are still around and are in fact, prospering.
Now, with real time expanding the perimeters of search, will we see similar verticals being pop up? That was the question I kept asking myself after talking to a couple of entrepreneurs who want to build alternatives to Twitter search. They argued that real time search shouldn't be confine to what Twitter provides. There is room for different forms of search that build on real time conversations.
This sounds reasonable to me and is worth supporting to explore how real time search will evolve. Currently in the real time search arena, we have general search companies like Topsy, Collecta, Crowdeye as well as vertical search like Twitseeker (for people search), TwitterJobSearch (for job serach), PicFog (for image search) etc. There is no clear winner yet but it is informative to watch how these services evolve.
The big challenge to me is to think about the context of which real time matters and therefore how real time search matters. Emergence plays a big part. When you want to know emerging thoughts, patterns, trends etc, real time search becomes critical. Think about reactions to product launches, about the spread of virus, about unfolding of events like sports, weddings, disasters etc. All these are context where real time matters.
I am sure there is more context surrounding real time search. What are your views?
