Nascent

Adjective:  (especially of a process or organization) just coming into existence and beginning to display signs of future potential.

Perhaps nascent isn’t exactly the right word for the fiftieth post here, yet it’s a good word none the less.  This word has connotations not only of something starting, but also that it has the promise of developing into something more.  The term doesn’t have the neutral to negative connotation of words like fledgling.  Something nascent is budding, like a leaf or a flower.
