Baader-Meinhof phenomenon
The Baader-Meinhof phenomenon occurs when a person, after having learned some (usually obscure) fact, word, phrase, or other item for the first time, encounters that item again, perhaps several times, shortly after having learned it. This is a specialised version of the effect of serendipity. (via Wikipedia)

Noted Baader-Meinhof, lets see what happens today, this is quite a frequent occurrence for me.
