Evolving language or laziness?

[Lorraine -dot- Lawford-McWilliams -at- ISOCOR -dot- IE]

I recently received messages which included the following clips:

>>.. are acceptable:
>>     Me and John are going to the store.
>>     Do you want to come with John and I?

>>Then there's "there's", which can take singular or plural objects for
>>many speakers.

>>This is obsolete.  Our evolving language dictates that there's and theirs
>>may be used interchangeably.  Thus theirs no simply rule for how people
>>use they're there's.

Of course our language must evolve to stay alive, but the examples given above
do not reflect a language which is developing and improving. Instead they
appear to be attempts by some writers to justify their own lazy style of writing. I
can't see any justification for confusing they're/there/their - it simply introduces
ambiguity and must be a nightmare for localization staff! In Britain and Ireland
such writing would be generally be considered  incorrect.
