Limits for self-promotion in answers
I understand that one should not excessively promote a product or a website via SO.
Yet, I maintain a technical blog with my own personal notes (and proper disclaimers when refering to external website content). This blog has advertising enabled. Sometimes, I put links in my answers here, to a relevant post in my blog (i.e., for example when my post contains a lenghty more detailed or complete explanation than would fit in a typical SO answer).
My posts often cover more than what is initially asked in the SO question. So, it probably would be considered off-topic or spamming to dump the whole content in SO answers here. I usually copy a relevant extract.
Is this practice of putting relevant links to some of my blog posts for more details OK with SO etiquette and policies?
