There are many people doing many things on-line that are self-serving, and annoying. While this may include people ranting about what annoys them, I'd like to mention two recent things I encountered for their excessive ridiculous-ity. They are so ridiculous, they are downright laughable. I'll start with the more obvious of the two.
There are people who buy domains for less than genuine reasons. These reasons include (but are not limited to) getting names that are similar to established names (like goggle.com for google.com), capturing potentially desired domains then reselling them at highly inflated cost (windfall profits), and just pushing adverts and fake search results to unsuspecting accidental visitors. This practice is called "Domain Squatting," or simply, "Squatting." This is first annoying to people who find themselves visiting such domains, but also, a secondary, and greater, annoying result of this practice is the "All the good names are taken" effect which prevents genuine use of such domains. Recently I encountered this, which I think displays that squatters have gone too far, and truly taken "all the good names":
My other annoyance for the day is DNS hijacking, specifically by ISPs. What this means for the common user is that when we misspell the name of a website domain we want to visit, and the domain isn't squatted, our DNS provider (usually our ISP) can 'hijack' that (errant domain) DNS-look-up request and redirect us to a (good-intentioned?) search page of there design. This can be good if it provides us with just the thing we were looking for, but usually, the results are not helpful. The annoyance here, is that it moves what we typed from our address bar, thus preventing us from making the correction. What would normally be a single keystroke correction now becomes a full retype of our intended destination. What pushes this annoyance to the ridiculous is my local ISPs idea of "opt-out". Not only does WindStream's opt-out option still clobber my address bar when I make a typo, but it spoofs an error page for the wrong browser! See how it looks in Chrome:
Time to use Google DNS!
