What makes you engaged?

I'm working up to launching my product and at the same time I'm hoping to build my Twitter account a bit.

I'm wondering what makes you engaged in following a profile or product. I think these are tips that can be useful for everyone on this platform to know about, as it might not be obvious.

I'll start;

I get engaged in following a profile or product, when there are regular but not spammy updates regarding that person's life or the development of the product. I'd prefer to follow a person behind a product, rather than a product page in most cases. What interest me are the motivating factors that make that person tick, seeing how they work/struggle (without whining) and what results that bring.
