As an IT person and having joined and contributing to learnflakes myself, I can safely say that learnflakes contents related with IT certifications are really premium and unmatched by others since they are focusing on this niche of contents.

Learnflakes will be best fit for people who are in IT or want to shift to IT world and pursuing IT related certifications, otherwise, it is better to join Bitspyder as the contents cater to broader professions
