Grammar and Spelling on a Website

Grammar and Spelling on a Website

I am a spelling and grammar nut, I have spent years writing Procedure documents and Training manuals and now focus on website content in our business.

One of my bug-bears is / are typing errors on websites and in books or documents.
 
Obviously in a book or document you can’t always point out the problem to someone but with a website you can.
 
A couple of weeks ago I offered some feedback on a website where the site had typing errors and some spelling errors that I thought impacted on the site.
 
I thought I was polite and commented a number of times that I didn’t want to offend but I obviously did because the email I got back about my comments was very rude, offensive and a personal attack against me as a person.  I must have really upset the owner of the website.
 
What do you think?  If you have a website, or print a brochure, or send out promotional material for your business would you like any errors pointed out?  Is it polite to proof-read others information and offer feedback or should you just keep your comments to yourself?
 
This is something I do for a job so it’s hard to not notice these things and hard to not point them out, and I think it’s important to ensure that a website looks professional and has accurate information. If something is grammatically incorrect, or spelt wrong, it makes me doubt the other information on the site.
 
Therefore I will continue to politely offer my thoughts and feedback.
