I like how most people blame bosses or scary big companies. No developers appear willing to admit that there is a large cohort of not that great web programmers who don’t know much (and appear to not WANT to know much) about efficiency. They’re just as to blame for the sad world of web software as the big boss or corporate overlord that forced someone to make bad software.
Usually bad web software correlates with bad content. Therefore having a slow device is an excellent filter helping to avoid garbage.
He said, with no irony whatsoever, that he didn't realise it would be so complicated and decided not to take me up on the offer. I suspect this attitude is not the unusual with one-man businesses that have survived just fine thus far?
