invoke-webrequest has a "native" short alias too: iwr. I like these native aliases because they use a consistent pattern of abbreviations for verbs and nouns, e.g., the same "i" for invoke is used in icm = invoke-command, iex = invoke-expression, ihy = invoke-history, etc.; then if you look at the nouns in one of those others (since invoke-webrequest is the only "webrequest" cmdlet), they're also consistent, e.g., gcm = get-command, shcm = show-command, trcm = trace-command.
