And as mentioned, check the .com and .net. If there is a well developed site, then you may not only have some competition but you might lose your own users because they might type in the .com first. If there is no web site, or its really just a holding-type page, then you would be fine with the .info as you build your brand. If there is a com or net site that is well developed, I would consider some other domains (maybe grab that particular .info, too, and point it to the domain you finally settle on.)
I asked initially about the search engine, and whether or not there was something I should know about a .info before going ahead and registering.
So, I guess if there's nothing odd about it, then it's thumbs up.
Other than that in SERPs it will work just as good as any other extension. An everybody from .NET to .ZW is loosing some traffic to .COM so if it is not com that you are buying .info will work just fine.
