Most working scientists I know at least browse the table of content of each new issue of their favourite journals, and read at least the abstract of anything that sounds interesting. So if you have something genuinely interesting to say and get it into a well read journal there is no reason to assume people won't read it. Also journals are indexed and archived in ways that personal web pages aren't, meaning if you get published, it will be a lot easier for scientists to find your article, both now and years into the future.
