Limitations of Wikipedia and Jimmy Wales

I was a tourist in NYC and wanted to learn more about the Upper East Side.  I read a multipage Wikipedia entry on it that gave general and historical information and then turned into several pages of lists:  the Upper East Side's public schools, private schools, coeducational schools, colleges, art institutes, museums, diplomatic missions, houses of worship, hotels, and finally more than a dozen films about this socially impressive segment of Manhattan.  Yet Wikipedia, as it often does, mostly told me what I more or less already knew and added some good if limited details.   It duplicated much of what my tourbook of NYC said.  Neither one got me to the spirit or heart of the Upper East Side, if it has either one.
Further websearching found a short piece I probably could not find again that said this is where "the New Yorkers that run the world live." It added that gentrification had recently led the Upper East Side to chew off from Spanish Harlem "96th and 97th streets," though it may not have phrased it that well.
In about 20 words of unfootnoted opinion using the literary license of overstatement and wisecracking, this web author had told me more about the Upper East Side than the uncounted minions of Wikipedia's founder Jimmy Wales had been able to say in 8 or 10 pages of text backed by 58 footnotes, that had surely taken them 1000 hours to write and edit.
I use Wikipedia "all the time" in spite of myself whenever I want basic, hopefully reliable information on a subject with which I'm not that familiar.  I'm glad it's there.  I've even donated to it twice--once I gave $3 and the second time I moved up to $5.  I have never been told by another breathing human that s/he donated to Wikipedia, which probably just tells you I'm in with the Out Crowd.
Yet I'd like to readily find other less-regimented essays on subjects, and may start a website to do just that in areas of my interest.  Maybe call it InfoGuy or Knowledge Page or ??  Question: how do you get into the web search results?  I see no evidence at all that the content of my blogs are ever considered in web searches, but maybe I need to look below the first 75 hits.
