Cleaning email archives over the weekend, came across emails from my first email account on in 2000 – the first time I got access to internet (though I had access to a PC since 1993 I believe – MS DOS, no HDD). Took me back to exploring my firsts on internet and here is list of what I can recall –

Service First Used

Chat service Yahoo Chat (2001)
Search / Directory service Yahoo Directory (2001)

Will add if I recall any others.
