Thanks for the reply weddingcakes. I did not know that about the theme. The reason I kept the default one was because I really liked how it looked.
I was torn about keeping the articles short and letting the images doing the talking or writing longer articles and decided to keep the articles short and sweet although I appreciate your point about thin content not being valued by search engines. I might try and write longer articles for future posts.
The social media plugins are something that never even crossed my mind for some reason! But it makes a lot of sense to include some. Thanks for mentioning that.
I really appreciate your tips, I am a novice and am slowly learning as I go along, so any tips, advise and criticism are very much welcomed by me.
