I like conciseness in articles, so most of my edits involve reworking existing text and removing redundant phrasing. I find the following phrases can normally be removed without any effect on the meaning of the text:

• It must be noted that
• Interestingly
• However,
• On the other hand
• Some point out that
• Of course,
• Obviously,
• It was reported that
• Sources revealed that
• In month/year it was announced that
• is known for

see WP:NOTED

I also try to move the focus of articles from the word to the topic. Removing phrases like:

• is a term that refers to
• describes
• refers to

see WP:NOTDIC
