1) information is frequently incorrect
2)"how to" articles are usually too brief and simplistic to be useful
3) often multiple articles covering same topic
4) directions are interrupted by advertising blocks and pop up ads
EHow should really be called "How-to for Morons". The articles are apparently written by the same folks who prepare those assembly instructions that come with cheap furniture kits. They're clearly paid writers who are copying information from other unreliable sources on topics that they know nothing about (click on the contributer's name to get their bio and you'll see what I mean). I've looked at dozens of topics on that site and the info is usually incomplete, inaccurate, or irrelevant to the question addressed. When it is accurate the instructions given are typically so generic and obvious as to be insulting; "to replace the battery in your remote control, remove the battery cover, insert new batteries, then replace the cover" - D'uh! Overall, I'd say eHow is even worse than message board sites like Yahoo Answers where at least you get several unreliable opinions to choose from.
