Sometimes I have posted my own blog post as an answer. While it is in line with the question and accepted as the answer, someone reported and some are down voted. I never used this site as a traffic source to my blog or never tried to spam this. I don't understand what the reason for this is. I don't think I have to rewrite my blog post again on this site.
If your article is relevant to the post - by all means give them a link!
If all you are thinking to post is -
Here try this - http://my-cool-blog.com
Then think again. Your post could very easily be come a target of some down votes...
There are a few things to take into consideration here -
- Proper disclosure of your association to the linked resource.
- Do not post link only answers. There are systems to prevent this now but in any case it is important to mention.
If you want to post a helpful link, make sure that your answer could still stand by itself in the event of link rot. If that URL happens to go down at some stage - will your answer still be helpful?
Always try to include as much information as is necessary and give the link for reference only. After all - we are in the business of bringing great content here as opposed to linking to great content outside of the site. I for one do not like to click though things when I am trying to ask or help someone on Stack Overflow.
