I am thinking of some earning.
The free apps I make will remain free. The website I make for them can accommodate some ads.
This is how the internet is now and I am planning to go along. I read about adsense.
I can apply but may not be approved,
My income is not guaranteed,
Google can disable adsense any time without reason,
May require extra work for the adsense to work.
Presently I am looking at it as an extra source of income, if possible with minimum work.
I will be happy to get comments for fellow developers who have experience in adsense, guidance etc.
