Little things make big differences. It helps hosts stand out from one another and shows that they're willing to put extra effort in, even if it's just for aesthetics. I know that Iniz and Backupsy have custom SolusVM themes and I think they're fantastic. It's a little upsetting that some hosts don't even bother to change the banner.
Typos, broken links, overused templates (and templates in general), badly-scaled images, etc. aren't deal-breakers, but they're certainly on my mind when I'm considering purchasing from a new provider. I'd be much more attracted to RAM Host, than, say, FlipHost, simply because they don't use some template (their site could use a make-over, though).
Also, regarding the aforementioned company: is it
Fliphost,
Fliphost.net,
FlipHost, or something else? They use several variations on their site -- it looks awful and that, combined with the use of a crappy template, makes me think that they're not worth my time. That's the sort of thing I'm talking about. Another example would be
this post. I mean,
uBuntu? Seriously? Do you even proof-read your posts? (I don't, but I'm not a provider -- I can get away with it!) Not to mention the lack of proper bullet points and such... We have fancy formatting options for a reason.
