You could just not read the articles that aren't interesting to you. Wishing that all/more of the articles are within your interests is essentially wishing that all/more of the people within the community are more like you. But in a community, that's unlikely.

Or, you could read some of the articles that aren't interesting to you, as they'll have ideas and problems that might be outside of your immediate experience and view. Who knows, they might directly or indirectly inspire some entrepreneurial idea that wouldn't have occurred to you otherwise.

Keep your eyes and mind open, you never know what problems you might solve.
