This type of decision might also impact Yelp or any others in similar businesses. Currently their API limits a top few reviews per business via their API, and also prohibits "scraping" of data in other means.
I was going to do some experiments with larger datasets from businesses in a region, but quickly found that's not possible.
I am not sure if it is true still, but I remember "regular" workers in Japan do not have to file tax. They are deducted from their pays and that's it. I think that will similarly apply to a very large number of population.
I also never liked really to use accountants, as they basically ask the same questions that I have to collect myself. Might as well use an online tool. Especially if most of the "W"s are already at IRS/FRB why do I even have to send the copies of them again. Why don't they just give me the partially filed XML/JSON to me to finish it off.
I did not have a fortune to get to know the LOGO or even SMALLTALK languages. By the time I've heard about it, it is the C++ or even C, and all us "professionals" dismissed this. I've just read up on the LOGO language on the Wiki, and some of its fortes are based on its roots in functional (encouraging recursions over a set) and declarative style. These people were already thinking about many years ahead for me. I would imagine my career would have been more enriched if I have encountered this early on in my life.
I would say Hangout is about the best and easiest for us and with external global people we work with and seems closest to Skype in terms of features. We like the desktop sharing and integrates fairly well with both iOS and Androids, can SMS and the most powerful feature to me is to call a user on their phone and add in.
