Hello @ericago, welcome to steemit. tags are a very important part of your blog, and you seem like you are going to be able to blog in a lot of different areas. The most import thing about tags is that the very first tag you use can not be edited out.
There is a relatively new group that has formed and support the active (exercising) steemit type post, they are @steemactivities and use the tag #steemactivities, they seem to be the curio's of the exercise world of post, so stopping by their page may be a good call.
I know there are a ton of food and travel groups on steemit, so you should have no problem finding one of those groups.
Also there is a very healthy community of filipinos on steemit, I believe they use the tag #steemph and their homepage is @steemph.
Music, there is a lot of music on steemit a good tag to search for music is #soundlegion, it is run by @soundlegion, they have a lot of contest and really support the music community.
Well I think that is pretty much it for now, look around at some of the tags, I am sure you will have no problem finding place to visit or communities to join. The greeters you have already met are all great groups.
Thank you so much for this! It's so much help. I can definitely grow more to the platform and the community. Thank you for the great tips and warm welcome,
All the best @ericago
