Hi MrAl,
The blogs are meant to be an online journal, with your progress and experiences related to electronics. It is sometimes a continuation of one thing or many things that you maybe doing. Articles are more factual and should be posted as completed documents (or as close to complete as possible) for example a complete circuit, a complete tutorial, or a complete block of code.
I would definitely recommend putting tutorials in the Articles section.
Let me know if you need any help.
Regards,
EM
